Hmm, that's odd. I don't think there is significant change of re(4)
in that time window. Would you show me the revision number of
if_re.c of old current?
What I wonder is why re(4) is child device of pci3 on recent
CURRENT whereas re(4) used to be a child device of cardbus0. Maybe
imp@ know more details on this. There was a change in pccbb(4).
