That turns on additional message enable bits, but for most drivers no
messages are associated with bits above 16.  Most messages are at level
6 and below.

The system logger is likely throwing away the messages.
In /etc/syslog.conf add the line
kern.*							-/var/log/debug

Which source code version?
You may be seeing a wildcard match line, or a line that identifies a
specific card release by the subsystem ID and recognizes other cards
with that primary ID with the next line.

(The Scyld PCI support code has the ability to do a partial wildcard match
e.g. "92?", while the PCI support code in the 2.4 kernel only does exact
matches for ID.  Thus the drivers from Scyld.com often have a final
line of the type "Match any 3Com NIC with ID 905*", since 3Com numbers
backward compatible NICs with the same prefix.)

It likely looks like an regular external PHY to the NIC -- there
shouldn't be anything magic.  If you are receiving packets, that
hints that no special power-enable bits need to be set.
