Yeah.  This is problem with how QtE wants to do things.  It wants a
preallocated section of RAM to write everything to, which shouldn't be
changes as far as I can tell.  Otherwise, I have to reimplement quite
a bit of code in QGfxRaster that I wouldn't even know how to start.
The real question still comes down to that I'm maintaining two copies
of the framebuffer, one in my driver and the real one handled by
DirectFB.  If there were some way for me to keep those synced (or
eliminate one) that would allow for accelerated operations.  Ideas are
welcome.

The docs for this area of QtE aren't very good.  Playing with
accelerations is on the list of to do's once I get the keyboard and
mouse drivers working.
