I have a Mac Mini with Intel 945GM chipset, including Intel 950GMA.
My sidux (or ubuntu) desktop display also flashes.
I found that flashing will stop (or get much less) if you edit xorg.conf and add in the line

Option "DRI" "false"

in the Device section, then restart.
However, this is not usable because X fails to render properly.
The symptom is an apparent freeze of the desktop (maybe the mouse will still move). If you switch to another VT (VT1) and then back to VT7 the desktop is live again and things you tried to do before have happened. The desktop stays live only for a minute or two before freezing again.

This (DRI?) problem is making X unusable on my hardware. It has only appeared in the last month.
