Not a big surprise on the latter as the code was written but never really
tested.

Video is a minor part of things, but it is starting to get annoying
to be able to do an entire cluster with LinuxBIOS all except a management
node, which needs video and a keyboard.

I would certainly be interested. I don't know if I could find the time
to do anything with it but I can at least collect up some code until
I have time to pursue it further.
