So I noticed. I've got quik mostly working now, but not for automatic
booting. I have to tell it manually where to look for the kernel.
(quik.conf doesn't seem to do anything at all - why is this?)

Yes, I had to figure out how to do that right away. Even with BootX, if
I didn't add a mode string and append ',noaccel', the text would be all
messed up, to the point of unreadability. Oh well, OFFB works for now.
I'm not planning on running X on it, or doing a lot of console things
with it.

You mean Cmd-Opt-P-R to zap the PRAM? Are you sure that Cmd-Ctrl-Power
enough times will get me an OF console? I have a small (<100 MB) OS 8.6
install that I was using to load Linux via BootX previously, but I'd
rather not mess with that if I don't have to.
