Dazza's right.. You can even have a full duplex 10/100Mb card on a switch
and yet if the NIC has been told to run at 10Mb and not 100 (as some cards
you can configure it) then that's what it's going to run at... what a
waste.....
A database of NICs is the only way to know.

It's not cheating - it's often the only way to find out - even under
"well supported" operating systems like WindoZe - interrogate the
hub/switch.
With all but the most advanced cards {3Com, Intel and the like}, there's
almost no feedback mechanism from the NIC to the OS - except to say "Yup,
I'm connected to the network". And even the advanced ones have to
physically disable the network to query the card, more often than not.
Good luck. If you find something, let us all know. :-)
