resume=/dev/sdx 

to the kernel line in /boot/grub/menu.lst

Sleepmode

Laptop Mode Tools

Works flawlessly. See Laptop Mode Tools.

CPU frequency scaling

Works as described in CPU Frequency Scaling.

Hotkeys

They work better after loading the thinkpad_acpi module, to assign the generated keycodes to their supposed functions.

tpb

Install tpbAUR, available in the Arch User Repository.

tpb (for Thinkpad Buttons) adds an on-screen volume bar for the volume buttons, THINKPAD button assignment, on-screen messages for Thinklight, (on and off) and more.
