NetBSD ported to the IBM 7044-270 (POWER3-II cpu)

Over the last few weeks, I have ported NetBSD/ofppc to the IBM 7044-270
POWER3-II based machine.  For those of you curious as to what one of those is:
=pseries&htmlfid=897/ENUS7044-270 (for above)

The machine has a 64bit POWER3-II CPU, which is what the modern POWER4 and
POWER5 chips were based on.  Currently, NetBSD only runs on this machine in
32bit mode.

The kernel config for the POWER3-based machines is GENERIC_B64.  It is
currently a separate config file because the 64bit bridge code in powerpc is
currently written to be incompatible with PPC_OEA.  I hope to fix that in the
coming months, and unify the kernels.  The stock version 1.8 ofwboot should
work on both however.

I'd like to thank Matt Thomas and Kevin Bowling for thier contributions in
making this port of NetBSD possible.

Some notes on the dmesg below:

1) I have only attempted single user mode at this point.
2) There is some kind of tty issue, so in order to boot single user mode, I had
to comment out tset from /root/.profile
3) The pciide isn't unsupported, there is no IDE header in the machine to
4) At this point I have only netbooted the machine.  Some minor work is likely
required to get this working from disk.
5) Its extremely likely that a 7044-170 will also boot.
