Ok, very quick update...no need to mess around with the eeprom. I just
received the official word on what will be supported. Since A2 is
pre-release, simply go to http://beagleboard.org/support/rma and fill
out the form to have it replaced with the current revision (A6).

This applies to *anyone* that received a pre-release A2 board.
