[ltp] Thinkpad X60s - brightness problems

[character]

I've got the same problem with my X61 Tablet. You may want to look at my
thread from monday (2007-10-15).

I don't know a solution yet except installing Ubuntu (or using the
xbacklight workaround).

Btw., using Ubuntu's kernel did not help, neither did Ubuntu's acpid,
acpi-support and/or gnome-power-manager.
