driver code from Linux for setting up font data in some graphics
modes?
Yes that would clearly be necessary, but perhaps a much more
streamlined mechanism would do for XEN.
If that's the case, I'm sure Gerd can point out the 'moving parts' that
we actually need to get basic text output working. I was hoping video.S
alone would be sufficient... :-)
