OK, I think I found a change in the FreeBSD driver which is meant to
fix "firmware handshake" issues with certain cards.  I also added the
ASIC revision number to a table so that it's not printed as "unknown".

New diff attached below, relative to 1.39 of if_bgereg.h and 1.222 of
if_bge.c.

Best regards,
