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.
