Works with no known issues. The point releases "Voodoo" and "Don't Panic" work without problems.
===Power Management=== 
====Suspend and Hibernate==== 
Works flawlessly.  See [[Suspend to Disk]].    Also known to work with [[Pm-utils]].
An easy way is use "suspend to swap" by adding 
to the kernel line inside /boot/grub/menu.lst. find your
for the swap Partition by
/bin/ls -lF /dev/disk/by-uuid/
and put it behind
You can use it perfectly with [http://www.archlinux.org/packages/?q=gnome-power-manager gnome-power-manager ]
====Laptop Mode Tools====
Works flawlessly.  See [[Laptop Mode Tools]].
====CPU Frequency Scaling====
Works as described in [[CPU Frequency Scaling]] with acpi-cpufreq as of 2.6.27-ARCH. Maybe you need to use speedstep-ich on earlier kernels.
They work better after loading the thinkpad-acpi module, to assign the generated keycodes to there supposed functions. 
As of December 2007, they don't work properly, since HAL is messing around with it's improvements.
tpb (for '''T'''hink'''p'''ad '''B'''uttons) is available through pacman:
pacman -S tpb
tpb adds an on-screen volume bar for the volume buttons, '''THINKPAD''' button assignment, on-screen messages for '''Thinklight''', (on and off) and more.
Yes, this didn't work from the beginning for me, but here is the solution:
keycode 77 = Num_Lock
Add that line to your ~/.xmodmap file.
Works fine with driver xf86-video-savage.
Fancy eye-candy like composition won't work with this card.
Here is my by hand written configuration for X that _should_ work. But since the recent update with xorg-server 1.5, the keyboard and mouse management has changed somehow, which means, the InputDevice Sections are in a reason deprecated or something else. Please refer to [[Xorg input hotplugging]] for further information.

Input detection on xorg-server 1.5 goes through hal, so start it before running X.
/etc/rc.d/hal start
Also add it to /etc/rc.conf
DAEMONS=(... hal ...)
Please not, if you've got an SXGA+, the graphics card won't support a higher depth than 16 as the memory can't house more colours.
