Short status update:  Project isn't dead.  But I'm busy with other stuff
and that will not change in August due to holiday season and kvm forum,
so don't expect new patches from me before September.

For anyone who wants play with this:  Pushed my current devel branch to

Indeed, didn't consider that yet.

Briefly looked at this a while back, figured doing this as "serial
seavgabios" would allow the reuse of some vgabios code.  On the other
hand the keyboard handling is easier to do directly in seabios: can
queue key events using internal seabios interfaces, no need to hook
timer irq (or better serial irq?).

I've noticed you've cleaned up vgabios a bit, possibly with the
intention to make implementing a serial seavgabios easier?  In case you
want give it a try:  Feel free to grab my branch and run with it.
