I suspect that may be the problem. The only real docs I could find were
for netbsd, and they said 3 things in 3 places (it'll Just Work, it
won't ever work, it'll work but needs a special kernel..)
I finally ended up just using the netbsd diskimage method (dd 2M to the
front of a drive, boot it, install to a 2nd drive, remove/reformat the
first..)
I'd much rather be using linux, so if anyone has a mop-ified kernel they
want to send me I'll be their bestest friend ;)

Yep, thats all I could find as well.
