I've been definitely aware of that potential.  I didn't look into it,
being too focused on getting custom resolutions working, but probably
will if I can find the round tuits for it - I'd very much like to know
how to accelerate the thing.  Even if it's only for screen-to-screen
blits, it would make for snappy scrolling, which would make cg14
console a _lot_ more usable.  I'm not sure they're using the blitter,
though; the console uses one of the 8bpp views of the framebuffer and I
suspect may be doing simple CPU-copy scrolling.  It certainly doesn't
scroll as fast as, say, the cg6 (which definitely does have a real
blitter, and scrolls very nicely as a result).
