I'm not familiar personally with the R31, but on several other models of
Thinkpad this is a BIOS setting if you're using APM.
If you're using ACPI, you can probably access this through ibm-acpi
Something like /proc/acpi/ibm/brightness or maybe /proc/acpi/ibm/video ?
(Disclaimer: I've never used ACPI on a Thinkpad because it always seemed
to lock mine up ... but ACPI works great on my JVC mini...)
