Mst@mellanox.co.il:

In 2.6.18, you have to change the disk mode from AHCI to compatibility mode
in the BIOS to make disk work after resume from suspend to ram.

After applying the following patch from Forrest Zhao
http://lkml.org/lkml/2006/7/20/56
both suspend to disk and suspend to ram work fine now in 2.6.18-rc6
with disk in AHCI mode (default).
Huge thanks to Thomas Glanzman for help in tracking this down.
This patch won't be in 2.6.18, but might make it in 2.6.19.

Older kernels don't work even in compatibility mode, you need this patch:

=== Linux X.Org driver ===
Supported by Xorg http://www.xfree86.org/current/i810.4.html.

=== Linux Intel driver ===
There is a Graphics driver for the Mobile IntelÂ® 945GM Express Chipset Family at [http://downloadfinder.intel.com/scripts-df-external/filter_results.aspx?strTypes=all&ProductID=2301&OSFullName=Linux*&lang=eng&strOSs=39&submit=Go%21 Intels Support Site]. This driver is just a snapshot of the Xorg/XFree86 driver.

In my case, the i810 driver recommended by multiple sources for this graphics card did not work, leaving a message of "No device found." Running against the generic vesa drivers solves that problem, but does not allow use of the external VGA port.

In Fedora Core 5 at least, the correct i810 driver can be obtained from the updates (in updates-testing as of Aug 15, 2006). With that, the i810 driver seems to work.

==== ThinkPad LCD ====
Display on the internal LCD works as long as you set the monitor settings correct.

==== External VGA port ====
Works. Dualhead is supported.

There are two options for running the external VGA port - either as a copy of the LCD (clone) or as a separate workspace. Here is an example for the separate workspace mode for xorg.conf for the X60s:
Section "Device"
Identifier "Intel Corporation Mobile Integrated Graphics Controller"
Driver "i810"
BusID "PCI:0:2:0"
Option "MonitorLayout" "CRT,LFP"
Option "DevicePresence" "true"
Screen 1
EndSection
Section "Device"
Identifier "Intel Corporation Mobile Integrated Graphics Controller External CRT"
Driver "i810"
BusID "PCI:0:2:0"
Screen 0
EndSection
Section "Monitor"
Identifier "LCD"
Option "DPMS"
EndSection

Section "Monitor"
Identifier "External CRT"
Option "DPMS"
HorizSync 28-75
VertRefresh 43-100
EndSection

Section "Screen"
Identifier "External Screen"
Device "Intel Corporation Mobile Integrated Graphics Controller External CRT"
Monitor "External CRT"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024"
EndSubSection
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Intel Corporation Mobile Integrated Graphics Controller"
Monitor "LCD"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "1024x768"
EndSubSection
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Default Screen" 0 0
Screen 1 "External Screen" RightOf "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
InputDevice "stylus" "SendCoreEvents"
InputDevice "cursor" "SendCoreEvents"
InputDevice "eraser" "SendCoreEvents"
InputDevice "Synaptics Touchpad"
EndSection

Here is the relevant text for running the VGA port as a true clone (so even things like Xine video playback appears on both screens) of the internal LCD display:

Section "Device"
Identifier "Videocard0"
Driver "i810"
BusID "PCI:0:2:0"
Option "MonitorLayout" "NONE,LFP+CRT"
Option "DevicePresence" "true"
Option "CheckLid" "false"
VendorName "Lenovo"
BoardName "Intel Corporation Mobile Integrated Graphics Controller"
EndSection

==== SVideo port ====
??

==== DVI port ====
DVI passthrough is only supported on the T60.

Linux support status is unknown

==== Suspend behaviour ====
* Required kernel parameters for suspend to ram: none
* Additional notes:
** switch to/from X11 to reinitialize display properly (stays black)
** DO NOT use vbetool to save/restore the video mode, this breakes resume!

=== ThinkPads this chip may be found in ===
* {{T60}}
* {{X60}}, {{X60s}}
