Subject: Preliminary support for MVME180 and MVME181 boards. On-board serial
 ports and VME controller are supported; tod chip isn't supported yet (coming
 soon). MVME236 memory boards are not supported and won't likely be (unless I
 get my hands on one).

MVME181-1 boots multiuser (slowly) with MVME328 SCSI and MVME376 Ethernet
despite only having 8MB of memory onboard.

MVME180 untested; might need tweaking to get MVME SCSI and Ethernet boards
supported.

Many thanks to Matti Nummi for lending me an MVME181 board.
