The Synaptics touchpad has a special register sequence that switches it 
to absolute-reporting mode.  The bonus of doing it this way is that 
Linux/XFree86-based operating systems get free absolute positioning 
support (the kernel PS/2 layer has touchpad support built in).  Windows 
is the only tricky part of this implementation.

The touchpad emulation isn't as hard as I thought it would have been, for this
very reason. I have the info query mechanism fully coded, and am working
on the packets themselves. So much bitshifting is tricky but not inheriently
difficult.

BTW, am I the first to try this? Or am I duplicating someone else's work?

It took 2 days, 10 hours, and 40 minutes to install win2k on qemu-softmmu
on a 200mhz Pentium I cpu. Emulated with 32 mb of RAM, though if I had to
do it over again I would have given it 64mb. Still takes 6 hours to boot.
