I  wanted to clarify on this point.  Understood as far as the above,
but the issue is that the PHYSICAL MAC was changed to
FE:FF:FF:FF:FF:FF.

 This went so far as to still have this value even after rebooting on
the standard kernel and then uninstalling XEN:

# dmesg | grep eth1
eth1: RTL8110s at 0xee156c00, fe:ff:ff:ff:ff:ff, XID 04000000 IRQ 22

What ever happened during the first boot of XEN caused a permanent
change to this NIC as far as I can tell.
