This is probably because mv643xx_eth now no longer fails registration
of the interface if no valid PHY could be found.  Gabriel Paubert
(CC'ed) had a patch for this that basically amounted to removing the
initialisation for eth1 (called "eth0" in the Pegasos platform code).
He's away for a couple of days but should be back soon.

Also, since the mv643xx_eth phylib conversion, it appears that the
PHY on the Pegasos board fails to initialise properly, and this can
apparently be worked around by turning the Marvell phylib driver off.
Are you seeing this as well?

thanks,
Lennert
