Reading more of this list, I realised that I needed rather less RAM in
this machine than it usually has.  Booting with 512 MB installed, I got
the results below.  Note that the second CPU didn't become ready on this
boot, but it did on an earlier one (which promptly panicked).  Also note
that pci1 and the Adaptec SCSI controller attached to it were never found.
I hope this is useful.
