Subject: Controlling backlight on thinkpad x60

Hi!

Some time ago, FN-Home/End just adjusted the brightness, and
/proc/acpi/ibm contained backlight control.

In 2.6.27-rc5, /proc/acpi/ibm does not contain backlight control and
/sys/class/backlight is empty...

(I do have CONFIG_ACPI_VIDEO disabled, it killed my machine last time
I enabled it, is it mandatory now?)
