Subject: X200: Brightness broken since 2.6.29-rc4-58-g4c098bc

Hello!

When using
  - vmlinuz-2.6.29-rc4-ikn-00058-g4c098bc or
  - vmlinuz-2.6.29-rc4-ikn-00211-g37bed90

the brightness of the LCD is almost off (lowest level),
although kernel reports otherwise:

[10:31] ikn:~% cat /proc/acpi/video/VID/LCD0/brightness 
levels:  20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 100
current: 100

Changing the brightness via echo 20 > /proc/acpi/video/VID/LCD0/brightness
only changes the value displayed, the display always keeps the same
brightness.

The last time I saw it working was vmlinuz-2.6.29-rc4-ikn-00001-gd5b5623.

Sincerly,

Nico
