PS/2 mice to help get them initialized. PS/2 mouse emulation now
defaults to streaming mode by default. See web site
http://www.computer-engineering.org/ps2mouse/ for more info. I was
wrong to assume PS/2 mice started in remote mode. Also a win for Windows
NT which does not bother commanding the mouse to enter streaming mode,
for this very reason, I assume. Removed "aux device reset streaming"
option, the above fix makes it unnecessary. Added debug print to AUX
emulation and INT 15h mouse calls for debugging.
