I haven't got the VGA working (hacking on the biosemu in
U-boot from time to time, will get there I hope). So keep this
patch out for now.

However I don't see how the VGA console is using iospace?
We set vga_base to the start of non-prefetched memory, and
assume the first slot is the VGA card, then it goes poking into
the screen memory or something... but maybe it's poking the
ioports in some runpath I can't see :-P
