So!
In the past week and two days of hacking on and off, it's come down
to 4 submits that got me past my last really ueberconfusing problems.
I was screwing up trapframe, PCB and stack stuff a little, as I
figured, and there still probably is something bogus there. But with
the changes in P4 submits# 54798, 54799, 54800, and 54801, I now get
all the way up to this in the emulator (going to try on my real IP22s
in a minute):

Note that I'm still not doing anything with caches, no semblance of
user-space support (though it should be easy, I've allowed for ASID
stuff, and the tlb miss handler is all that would change an obscene
amount)... But hey, whee.
Now I'm debating md and userland, vs. device support then userland.
Thanx,
juli.
