You mean you've been changing virtual consoles as fast as you can on a
SUN and an SGI? Nah.... Didn't think you tried that.

Sun and SGI have a frame buffer that is graphics mode only, and
doesn't need changing from VC to VC.

I think that things are "implementation issue": If an Xserver would:

- on switch away, only tell the kernel that the switch is done
after everything is actually done. Discard keystrokes recieved after
the switchaway was initiated.

- on switch-to-X, first tell the kernel (keyboard->raw mode) and
process keystrokes once your're fully switched.

then, everything would be just fine.....
