iBook G4: first wakeup has black screen

With 2.6.11-rc4, sleep seems to work pretty well. There's still problems
with disconnecting USB devices while the machine is asleep, but that's
nothing new.

I've noticed one thing though: The very first time I wake the machine up
after sleeping the screen is dark (backlight off?). If I put it to sleep
and wake it up again everything goes back to normal.

The machine is an iBook G4 1.2GHz:
0000:00:10.0 VGA compatible controller: ATI Technologies Inc RV250 5c63
[Radeon Mobility 9200 M9+] (rev 01)

Has anyone else seen this before?
