In newer drivers, this would be done in a board specific file.  As you
can tell, this code enables the Ethernet PHY.  I don't understand
why that extra 'add this' is necessary.  That does some PCMCIA signal
routing to IP_B5, which should not have any effect on the Ethernet.

What revision of board is this?  I have RPXLite's that I boot from
flash all of the time without trouble.
