OpenSUSE Hardware :: Multiple With 'Intel' Graphics Driver In 11.4?

I've been using Mandriva (and predecessors) for ten years or so, but that distro really seems to be dying at the moment. Consequently, I am trying to move over my various PCs to SUSE. I've started with my EEEPC 901 which has a 945GME integrated graphics chip. Using Mandriva 2010.2 it works fine and I can have desktop effects (built into KDE) running with no problems. However, with KDE on openSUSE 11.4 I get irregular freezes, although I can still work within the focussed window. Moving around though, clicking on other parts of the desktop etc. doesn't work, then after a few seconds they all happen at once. I am getting the following error multiple times in the X log, which I suspect is associated:

Code:
EQ overflowing. The server is probably stuck in an infinite
loop.

I note this supposedly fixed bug report that may be relevant:[URL].. Secondly, I am getting hopeless 3D speed (glxinfo reports SGI and has all expected output). Desktop effects won't work at all, on boot it pops up a message saying they are disabled as too slow. I know it isn't a benchmark, but glxgears gives about 50, it used to give over 500. I remember a few X versions back having to enable UXA mode instead of EXA in the 'intel' driver, but presumably that is no longer needed and I cannot see any effect of doing that now (in the xorg.conf.d device file). According to the X log, X is definitely using 'intel' driver, not fb etc.
