Hi James,
  if you want, you can take a look at 
ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/2.4.0-test7-vgatext.gz.
It contains patch for 2.4.0-test7 which adds textmode and 8bpp modes
to vga16fb driver (8bpp of course only 320x200 cfb8 or 360x480 planar 8,
as standard VGA knows).
  Text mode support only 256 characters, but if there are request to
change it... Also, hardware VGA cursor is not utilized. This patched
driver uses vga_io_{r,w} macros to access hardware registers. So converting
to vga_mm_{r,w} or to pure vga_{r,w} should not be too hard.
  Although I think that we should leave VGA alone. It is just too painful
to try multihead on such hardware...

P.S.: I'm using this vga16fb to get 800x592 textmode on my notebook.
Fortunately my LCD does not care about screen refresh...
