I modified a second board, and it wasn't quite as
successful.

The signal levels from the PHY all appear to be within
spec for the MPC8349EA.

Unfortunately we can not probe the pins on the PowerPC
BGA on the MDS board to compare with our board. The
MDS board has the processor socket housing covering
the BGA pins.

We'll continue modifying and testing ... we'll
track it down eventually :)

Cheers,
Dave
