I have the problem as well:

Sony VAIO VGN-C1S with Intel gma 950
Ubuntu 8.04

Happens not very often, perhaps once every two weeks the external monitor flickers at unregular intervals. After some time the monitor goes black and only a complete restart will help.

Tried the solution posted in the Blog post as mentioned above and turned of FramebufferCompression. I will report if it happens again.
