There are already a couple ways to do this. One is that LibbGI
can use SVGALib as a target. The other is "suidkgi", which is KGI+KGI
drivers and runs in userspace.

This isn't the case right now, but the accel driver takes up very
little space, 5-10K at most.

EvStack (which is now called GGI Console) will be able to bind
together an arbitrary collection of input and output devices and call that
a console. Multiheading will be a piece of cake.
