Has anyone posted some public source code for svga mouse drivers at an
FTP site? So far the only documentation I've found for unsupported modes
is an _extremely_ brief article in the MicroSoft KnowledgeBase. In
particular, how do you keep track of the mouse position in unsupported
video modes? The MS snippet indicated that the x (CX) and y (DX) parameters 
would not work and the delta_x and delta_y in mickeys had to be used--but 
when I did so, I got a pointer that kept going down when the mouse moved up, 
etc. I wound up using the pixel coordinates returned in CX and DX after
all, and they worked (at least in the mode I was in, which was a TSENG
4000 640x480x256 mode).

I get nervous using something that's not supposed to work...
