Even the 21143 card?

Hmmm, the MXIC cards that I have, 98713 and 715, are both keyed for 5V

Flipping through the cards recently tested and not yet returned to the
card rack here are a tulip cards I encountered keyed for both 3.3V and 5.0V.
The Linksys NC100 and LNE100 v4.1
The Znyx 21143 card

Keep in mind that a chip may support 3.3V operation, but be paired with
a 5V only transceiver.  Wake-On-LAN support provides only 5V, so a 3.3V
transceiver might be an issue.

BTW, there is no market for a 3.3V-only 32 bit card.
