restrict the FSTATE_STAR prohibition (and panic) to the i386 only. Cloning

Browse Source 
devices actually do make sense on indirect-config busses, because you
might be able to have more than one of the busses!  In addition, they're
useful because they don't require unit numbers to be wired down, so you
could e.g. have vga* at indirect? and vga* at direct?, and have the first
one found be unit number zero.  Finally, devices which can divine their
own ports numbers, etc., actually should be cloning, even if you know you'll
only have one bus that they can live on.
