Grinding Teeth

For some months now I’ve been gurning, wincing, grinding my teeth and scowling at my macbook over the completely broken OpenGL support on my intel graphics chip. Last night I decided to try anything and everything in order to get something working. Eventually after trying each and every intel driver option in my xorg.conf I managed to get some GL output.
Weird interlaced GL output
For anyone else who’s suffered from this bug the following options in the device section of xorg.conf allow you to get more than simply a black box;

Option "TripleBuffer" "true"
Option "PageFlip" "true"
Now, although any OpenGL applications/screensaver output looks like this, compiz on the other hand does actually work surprisingly. It is pig slow, probably a tenth of the speed I’d expect on this laptop but at least I’ve made some progress.
If anyone has any clues as to what is actually happening please let me know. It’s now gone past the point of annoyance to simple curiosity…
