vbios 

After a suspend/resume cycle, my brightness is stuck to some low value which
can't be changed with the brightness buttons or nvapoke 0x61c084 0x80000200.
Both of these do work before suspend.

Output of "nvapeek 0x61c084" (both before and after suspend/resume):
0061c084: 00000401

Attached is /sys/kernel/debug/dri/0/vbios.rom.
