Oh, Linus Åkesson's stuff is awesome.
Recently I read about the Macintosh Display Card 8/24 GC, which is a nubus display card that uses an AM29000 RISC CPU to do quickdraw operations on its framebuffer. One of the particularly neat things about it is that it can operate as a NuBus master, which allows it to accelerate other dumb framebuffer cards you might have installed. Very cool! There is a MacTech article about it here.
Ideally I would like to do something a little like that, but I can't seem to get around needing a dual port RAM, and I don't have enough control over the external bus to do a funky workaround. Argh.
