This slipped under my radar, and I'm only just now finding it again.  Have your issues been resolved?  If not, could you send a bit more of the boot log?  There should be a little more if the PHY was not found.  If you were operating with a fixed PHY setup before, then the generic PHY driver (which will automatically bind to your PHY) should suffice unless your MDIO bus is broken.
