I wrote a userspace touchscreen driver years ago that worked on win95-> and would probably still 
work on the latest and greatest.. it was actually a userspace application that talked to the 
touchscreen over rs232.. I could probably modify that to work here..

I'm gathering that if I read from 0xbad I'm going to get the absolute mouse position and by writing 
to 0xbad I can turn the sdl cursor on or off..

What happens with mouse clicks? do they still come over the ps2 interface?
To make this work with what I have in mind we'd have to disable the ps2 position updates to the 
guest when the mouse app starts on the client and use the read port to give position updates. We 
would still pass the clicks through the ps2 interface however.
