Well I'm happy to report that removing fdc0 and fd* from the config
made it boot happily.  (Same as for Jan08 snapshot) I was in a rush
Friday so didn't followup then...  When I left it was compiling
/usr/src/lib but I see it died at

lib/libc/net/linkaddr.c:95: invalid operands to binary -

it will have SUP'ed again since then so I'll try again.  All in all
though Alistair's build recipe looks fine for sparc as well as i386.
