Great!

Can I check it in at vger after I have fixed the FBCON_HAS_* things?

No problem.

Already fixed in vger: there's now a clear_margins() routine for
cfb{8,16,24,32} that clears the margins if the screen resolution is not a
multiple of the font size.

Fixed in vger, I think. And also with Martin Mares' latest patch set.

You can round it up, or just don't use acceleration.
Without acceleration, but with dispsw->scrollmode = FBCON_REDRAW, scrolling is
even faster than with acceleration, at least on my ATI RAGE II+. I'm starting
to think that text mode acceleration using bit blit is useful for slow buses
(e.g. ISA) only, not with PCI.

The console doesn't care about the horizontal virtual screen.
