IBM ThinkPad T23
Works with no known issues.
Suspend and Hibernate
An easy way is to use "suspend to swap" by appending
to the kernel line in Template:Filename
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.
They work better after loading the thinkpad-acpi module, to assign the generated keycodes to their supposed functions.
As of December 2007, they do not work properly, since HAL is under heavy development.
tpb (for Thinkpad Buttons) 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.
If not already working, this key may be configured by adding:
keycode 77 = Num_Lock
Works fine with driver xf86-video-savage. Eye-candy like compositing will not work with this card.
Please note, if you have an SXGA+, the graphics card will not support a higher depth than 16 bit.
