I think the radeon / ati driver picks up VGAHW support via a #define in
xorg-server.h which is included from it's local config.h

I've tested the radeon driver with a radeon 9200 agp and while it still has
the 'dark font on console restore' issue that the r128 driver also has in
non-16-bpp modes (I've been meaning to look at this in more depth at some
point, but haven't gotten the round-tuits), but otherwise restore VGA mode
fine.

To your latter point, I think Jared McNeill has convinced me that The Right
Thing is to make the vga(4) driver restore proper text mode settings when
it gets control from the X server again.. but again, I haven't had the time
to look at this.  Certainly Linux takes this path (hence the wealth of text-
mode restore bugs resulting from "All the world's a Linux" mindset ;)) and
I've been told that OpeBSD does as well, so there's likely code there we can
steal.  I won't preach further until I have something to show off ;)
