That's what I've been using. You can get that with 1MB VRAM as well, but
I think you have to tweak the VIDC BandLimit file.

In that case it looks like I don't have wd0e mounted on /usr. If what I
tried to do worked properly I should have partitions for root, swap, var
and usr. Wouldn't that make usr wd0d (again, by my limited
understanding).

Yes, I've been doing that.

Yes, but when I was in my local library a few months back I noticed a
nice little Unix pocket book, and I thought, "Ah, that might be handy if
I ever install RiscBSD." ;)
