I have the following problems with my Radeon FireGL Mobility T2 (IBM
Thinkpad R50p):
1) there is no console blanking nor backlight off powersaving with
fbconsole (no X running nor started since boot)
2) after an acpi suspend the backlight goes back on but there is no data
displayed on the screen (no X running nor started since boot)

If more information is needed for diagnosis then please email me.

used kernel versions: 2.6.6 2.6.7 2.6.8.1 2.6.8.1-mm3
