Yes :( The good news is Vojetch is working on something that does use
multiple mice. Even regualr mice.

Vojetch is also working on that :) Last time I tried it I got two ps/2
keyboards to work (one was in my ps/2 mouse port).

Take a look at Vojetch work.

By the way Vojetch work is based on GGI console. He thinks it was really
good work. The only real difference is its less streams orientated. Linus
hates AT&T Streams for some reason :( Vojetch is working on the keyboard
part and I'm working on fbcon so we can have a true multiheaded system.
Note also the newest 2.3.x kernels have real resource management now. Its
being worked on for other types of buses. So linux is finally evolving to
the KGI level.
