You were right, it didn't help.

Ok, I've got more information.

As a reminder, this is a 8-stable snapshot from December,
with if_bge and brgphy from 9-current as of today.
(In fact I just copied the whole mii directory, not just
brgphy.)

The result is that there is no brgphy found at all, so
devinfo doesn't list it either.

Next thing I did was to apply the patch from PR 122551
because the problem description sounds somewhat similar
to what I have (though not identical).

The result:  Now a brgphy is found, but it lists only
copper media, not 1000baseSX.  I'm pretty sure this is
a fiber PHY, though.  So, still "no carrier".  :-(

Here's the information you requested (with the patch
from PR 122551) ...

Actually, the blade (its an IBM BladeCenter HS22) contains
four NICs:  two bge(4) and two bce(4).  All of them are
fiber (1000baseSX).  None of them work.  I can open a new
thread for the bce(4) issue, but first I would prefer to
get the bge(4) interfaces working.
