After much hackery, and assistance from a few people, I've gotten the IBM 7024
model E20 to boot and run NetBSD successfully.  Here is the dmesg from the
boot.  I will also send patches against -current in my next email.  The machine
comes up onto an NFS root just fine, and I have full access to the disks and
network, so I think multiuser will not be a problem from the internal drives.

Also.. this should work on a 7024-E30 with very minor changes.  Namely we need
to add an additional model in the platform struct of ibm_7024.c
