No, unfortunately this will never work, even if we had all the values (where
is the frame-buffer address?).

I tried it first with hardcoding width, height, depth and fb-addr in
genfb_init(), and the driver thinks it is working, but not really. The
display is still in text mode and not in frame-buffer mode, and I see no way
to switch that on the Pegasos. :|

Another problem would have been copyprops(), which thinks that the
console_node must have "pci" as parent, which is also not the case here.
console_node is "/bootconsole", which has no parent.
