adding driver-level linedraw, clipping, and blit code has sped up my
25MHz target significantly. there were also some speedups made for text
draw which were merged into the tree a few years back.
I've put a tarball of the our branch at
http://frye.com/~aaron/microwin-frye-nanosteve.1.tar.bz2 .
I have been working on merging with CVS and porting our local hacks
(including fast linedraw) to other framebuffer devices. I'm almost
there except stipples and dashlists are still broken.
