Before installation

I switched to "discrete graphics" (Intel 4500MHD) in the BIOS. I didn't want to use with the ATI card because of the driver issues. After installation, I reverted to "switchable graphics" and it works well.

Installation

I used an (amd64) USB image (hd-media) and the Lenny RC1 netinstall ISO. The install sequence went flawlessly. The Gigabit Ethernet adapter was detected and configured. I installed without X, switched to sid in sources.list and then went for X and Gnome.

After installation I compiled a vanilla 2.6.28 that I'm currently running.

Working

More or less out of the box with the 2.6.28 kernel:

• Gigabit Ethernet (e1000 module)
• 5300AGN wireless (iwlagn) with CRDA userspace regulation
• Intel graphics, X driver from sid repository
• suspend to ram (echo mem > /sys/power/state OR Fn+F4)
• sound (HDA) + volume control buttons
• Bluetooth
• webcam (UVC driver, tested with guvcview)
• card reader
• watchdog timer (iTCO_wdt kernel module and the watchdog daemon)

HDAPS

The source package in the sid repository for tp_smapi is a bit outdated, so I compiled and installed using the tarball for SourceForge.

In order to get the OpenGL visualization utility (hdaps-gl) and the head parking daemon (hdapsd) working properly:

• create /etc/modprobe.d/hdaps , containing:

options thinkpad_ec force_io=1
options hdaps invert=1

• add the following line to /etc/modules:

hdaps

• install hdapsd, which creates the required udev rule (/etc/udev/rules.d/z60_hdapsd.rules). I used the 1:0.0.20081004-1 version of the package, as it was required by the new sysfs interface in 2.6.28.
• However, if you don't want hdapsd (i.e. just want accelerometer data with no head parking), you can create a rule containing:

KERNEL=="event[0-9]*", ATTRS{phys}=="hdaps/input1",ATTRS{modalias}=="input:b0019v1014p5054e4801-*",SYMLINK+="input/hdaps/accelerometer-event

• install hdaps-utils

Hard drive issues

Running hdparm -i /dev/sda gave me the exact model and firmware version of the disk (Seagate Momentus 5400.4 SATA 250GB):

Model=ST9250827AS                             , FwRev=3.CMF

I modified (in the kernel header ata.h) the ata_id_has_unload() to print the hex value of the ATA_ID_CFSSE word (Command Feature/Set Supported Extension). The result was:

[    3.910056] ata: CFSSE 4000

According to the ATA-7 spec, the 13th bit should be 1 if the drive supports "IDLE IMMEDIATE with UNLOAD FEATURE", and here it is not the case. Therefore, it is quite clear that the drive reports it has no support for the feature.

However, doing a manual write to the sysfs file (like echo 10000 > /sys/block/sda/device/unload_heads) does NOT cause an error and causes the drive to park the heads (the specific sound is clearly audible).

All in all, hdapsd has the expected behavior, regardless of the hard drive bug.

Not working

• mute button
• fingerprint reader, seems there's no driver yet

Not tested

• DisplayPort
• modem
