SubjectRe: Brightness control fails between 3.6.8 and 3.7.0-rc7 (Intel 915/Dell Vostro 3560)
I've narrowed it down to sometime between v3.6.8 and v3.7-rc1.  So none of the v3.7 series will work with this GPU/panel.

I don't think it has anything to do with the dell modules since they haven't changed.
