I'm glad you were able to find the problem.  This kernel probably lacks 
the patch to handle the persistent MAC address.  It does, however, have 
support for Flattened Device Tree, and a patch to read a MAC address 
from the device tree, which could be used to make the MAC address 
persistent.

I have resync'd the xpfa yum repo for f13 and verified 
kernel-omap-2.6.40.3-2.02.fc13.armv7l.rpm is there.  I updated the panda 
to 2.6.40.3-2.02 and it boots and runs without issue.

This version includes Mark Salter's patch, so you'll want it before 
doing the USB storage performance testing.

Sorry for missing this earlier.
