Could be ... I don't know.  The driver checks whether dynamic standby
mode is enabled in the EEPROM at attach time, and if it is enabled
the driver emits that message and turns it off again.  I only saw the
message the first time I booted FreeBSD.  So if the BIOS is overriding
the setting, it's not doing so by scribbling in the EEPROM.

I've definitely got a 100 Mbps full-duplex link.  I haven't tried it
at 10 Mbps, and I wouldn't bother using them at that speed even if
they worked perfectly.
