[opensuse] XAA perfoms better than EXA but has bugs (Intel graphic card)

Hi,

By default openSUSE 11.1 brings Xorg using EXA as accel. method.

I have a Thinkpad T61 with an:

00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (rev 0c)

Always after I enter my password in KDM to login the screen shows a "visual
noise", and also sometimes.

But worst of all I find the performance lower than when I configure it to
use XAA.

So I change back to XAA in xorg.conf but the problem is that I cannot use
suspend/hibernate if the Xorg is running with XAA (the active graphic
desktop session crash returning to KDM after resume from suspend/hibernate);
and sometimes I have experimented complete hangs (I think caused by XAA
because they don't happend with EXA).

The performance with XAA is much much better than EXA, but I must hope hangs
and to disable suspend/hibernate if I want to use it (fact that I can't
consider).
