Yes, this will work, if it's a card with a writeable MAC address,
you know the MAC address on the old card, the old card also has a
writeable address, and you know how to reprogram both of them.

Now consider that this is probably outside the realm of possibility
for someone who didn't even know that the MAC address might be used
this way, to the point where they needed to ask on a mailing list
why things weren't working... ;^).
