A fix/workaround for the underlying problem was commited some time
ago and MFC'ed to RELENG_6 on November 30th so the December 6.0
and 7.0 snapshots should boot just fine from stuff attached to
the on-board ESP in U1.
I also did a driver for the on-board Ethernet NIC, with some luck
it'll be in 6.1.

AFAICT there's no such thing like a SBus Creator card, all have
UPA connectors (which come in two different shapes) and U1 don't
have UPA slots. Actually I think the only graphics cards supported
in U1 are the TGX and TGX+ variants of the CG6 familiy, at least
the GX and GX+ ones are electrically incompatible with SBus in U1
and you also can't plug the latter into a U1 unless using a saw
(that's probably also true for the other SBus graphics cards built
for the sun4u predecessor).  I hope to have a driver for the CG6
ready for 6.2.
