==== Linux ====
Most of the laptop features are currently supported by Linux. Kernel versions 2.6.17 and later are recommended.

==== Hardware support ====
===== Sound =====
Sound works with the snd-hda-intel module in the Linux kernel. Be aware that '''disabling the modem''' in the BIOS may '''break''' sound.

===== Virtualization =====
[[Intel Core Duo (Yonah)]] and [[Intel Core 2 Duo (Merom)]] supports Intel VT-x, but Z61t BIOS [http://forum.thinkpads.com/viewtopic.php?t=31049 disables it], rendering this system unusable for [http://kvm.sf.net KVM] or Xen with unmodified guests. Avoid this model if you care about fully exploiting CPU features.

[[UPDATE 06/06/2007:]] Version 7FETA0WW (2.18): (New) A new Intel Virtualization Technology option is added to the CPU of the Config menu in BIOS Setup Utility. Note: The option is set to "disabled" after the BIOS update.

===== IRDA =====
Make sure you either explicitly enable or disable the IRDA functionality in the BIOS (instead of having it be enabled but off). Otherwise the kernel IRDA driver will OOPS. Other than that it works fine.

===== Graphics =====
Requires xorg-x11 >= 7.1<br>
xf86-video-i810(xorg i810 driver) >= 1.7.0<br>
915resolution.

===== 3-in-1 card reader =====
Support for the built-in memory card reader is provided by the [[tifm]] drivers.

===== ACPI =====
====== Suspend ======
As of kernel 2.6.17, suspend works, with the caveat that the SATA controller is set to compatibility mode in the BIOS (instead of AHCI mode). This is due to the fact that the kernel dosen't exactly support suspend/resume in the AHCI driver yet, and the AHCI module fails to turn the hard drives back on at resume time.

Patches for AHCI suspend are aviable at the following urls:

[http://marc.theaimsgroup.com/?l=linux-ide&m=114959199902868&w=2 Patch 3]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114959199906103&w=2 Patch 4]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114958984425832&w=2 Patch 5]
[http://marc.theaimsgroup.com/?l=linux-ide&m=114958984425521&w=2 Patch 6]

====== Problems with Drivers ======
Certain driver modules are known to exhibit problems on suspend. These are:
* ipw3945: Intel wireless driver.
* sdhci: SD host controller interface driver.
* [[tifm]]: Memory card reader driver.
Depending on which combination of kernel and driver versions you're using, the above drivers may cause you problems. These drivers should be unloaded prior to suspend or your system may hang, requiring a power-cycle.
