I ported the AS1000/AS1000A support from NetBSD.  I don't think the
1000A support has been tested yet.

I think I may have found a bug in the port of the interrupt code.

I can send you a patch (below), or I can build you a floppy to use to boot
4.2.  

If you'd like a floppy, please describe your hardware (srm "show conf")
so I can strip out some devices from the config file -- I cannot seem to
make the BOOTMFS kernel fit on a floppy.  I have no idea how David did
it.
