Suse 11.1 RC1 and intel i845 built-in video card

Hi
I have just upgraded a Dell Dimension 2400 PC to 11.1RC1. This PC previously worked nicely with 11.0 and before that 10.3.
Now, my built-in video card is not recognised (gets set to framebuffer).

If I run :
sax2 -r -m 0=intel
or
sax2 -r -m 0=i810
the X server starts up then crashes the machine.
In fact, the problems sound similar to this post on the forum (but I am using 11.1RC1 not 11.2alpha) :
OpenSuSe11.2 Alpha Probleme bei Installation sax2+i810 - openSUSE Forums
Yast hardware information reports the video card as an intel i845.
smoltGui reports it as an 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device
Did the DVD upgrade from 11.0 backup the old xorg.conf somewhere ? Maybe I could get more info from that ?
Does anyone have any idea what else I can try ?
Thanks!

Ok, I found the buglist and it is a known issue.

Putting :
Option “ExaNoComposite” “true”
in an old backup of xorg.conf seems to have fixed it.
