   Did you get anywhere with this Ben?

Not yet.  Maybe tomorrow or Saturday.  I simply haven't worked on it yet.

   How close are the variable bit width drivers to being usable (I'm assuming
   they're the bogl-tcfb and bogl-pcfb drivers)?

They don't work now?  I haven't tested them (they're by dhd@debian.org
not me), but I can now that I have matroxfb set up on my main machine.

   Also, am I right in thinking that the VGA16 will still require a
   separate driver due to it's non-linear architecture (which would
   also seem to be why GGI won't work on top of it)?

Yes.  I'm not sure what pixmap format I'll use for it yet; probably
interleaved planes.  I think that's the most hardware-efficient way to
blit the bits.
