Congratulations on going stable!  I am experiencing this issue as well, and
this is the one bug keeping me from using Nouveau.  I would really like to have
xrandr 1.2 support, so please let me know if there is anything I could provide
to help troubleshoot this.

Notes:
Thinkpad W510

01:00.0 VGA compatible controller: NVIDIA Corporation GT216 [Quadro FX 880M]
(rev a2)

When using the nvidia driver, the following option needs to be added to the X
config file.
Option "RegistryDwords" "EnableBrightnessControl=1"

When using the nouveau driver, brightness controls works fine.  After suspend
and resume, brightness stuck on max.
