Cool. Speaking of mips, we have the merged Juniper 6.1 mips code dump
and the community mips2 code base booting on Cavium hardware and the
malta board in simulation. I hope to test it out on ADM5120 based
hardware sometime this week.

I know that John Birrell sent me a nor driver that had been
geomified. It was on the order of 500 lines or so, but lacked write
support.
I'd be very interested in having a more complete driver in FreeBSD.
It is useful in many contexts.... Ideally against -current, but if it
is a choice of between 'a diff against 6.1' and 'nothing' I'd take the
former.
