I have the exact same problem as Auke, for as long as I have the laptop (about
2 years). This problem used to occur with the blob as well (if I remember
correctly) but it does work now.
I am using an HP Elitebook 8530w (nVidia Corporation G96M [Quadro FX 770M] (rev
a1)) on fedora 15.
dmesg says: nouveau 0.0.16 20090420
yum says: xorg-x11-drv-nouveau.x86_64 1:0.0.16-24.20110324git8378443.fc15
mesa-dri-drivers: 7.11-1

Brightness control does not work with this option for me.
