re: kern/57947: autoconfig errors probing card reader

[matthew green <mrg%eterna23.net@localhost>]

FWIW, this is not new behaviour.  i see it on some card readers
and not others.  some attach the various ports, sometimes as
separate sdN devices, sometimes not, at initial probe time, and
some only attach the sdN when you insert a card.

i'm not sure what the best way to handle this is, but it is in
some sense expected by some devices, so perhaps we can make the
message debug-only in these cases (if we can be sure?)
