compiz - Jan 2007 - Problems with Mesa 6.5.2 and open drivers ("driving" me crazy)

OK,

I'm sure this has been mentioned before but I'm really struggling now!

The problem is best described here:
https://bugs.freedesktop.org/show_bug.cgi?id=9456

I've added my own Mandriva cooker bug here:
http://qa.mandriva.com/show_bug.cgi?id=27971

People also make reference to the issue here:
http://forum.go-compiz.org/viewtopic.php?t=309&view=next

Has anyone got any ideas?

Col.
