Blank screen on Mac Mini running Boot Camp 3.1 with XP SP3

After upgrading from 3.0 to 3.1 of Boot Camp I now am getting a blank screen after Windows finishes it's loading screen.

Booting to safe mode works.

I have tried uninstalling 3.1 and reverting back to 3.0, but the issue remains.
I uninstalled and reinstalled 2.1 (from a older system disk I had around) and the issue seems to be resolved however the refresh of items and windows on the screen are very slow.

I have isolated the issue to the NVidia drivers, however I am unable to find any besides the bootcamp ones that seem to work. I've read through the forums and people have mentioned downloading drivers for other models but not the Mac Mini.

So, two questions that would be very helpful in my quest to fix this:
1) Anyone know where to get the latest working Nvidia drivers for the new Mac Mini (besides bootcamp)
2) Anyone have a good utility or know of a good cleanup utility to get rid of all the previous nvidia drivers all over the place and in the registry? I read about a few, but it would be nice to know which ones actually work with bootcamp/xp, etc.

Thanks for any assistance on this!
