Vista - SIS 650 Graphics Chipset Driver issue

Since the December 05 CTP version, I have been having issues with the bundled
Vista Driver for my Graphics Chipset.

I am having to press F8 at boot, to boot in Low Res mode (640 x 480). Once
I have logged in if I then change the settings in any way the screen goes
black and I am unable to do anything, except reset the machine.

Pre Dec 05 builds were fine and allowed me to go to 1024 x 768 with no issues.

I currently have the chipset configured to use the maximum 64mb of RAM
available.


Please help as this is really bugging me, and I stopping me really getting
to grips with the system and fully testing it out.


Cheers

Dave
