This change looks very strange.

1) Did you try your tests on the reference 405GP board (Walnut) ?
    Maybe it's not a driver problem but your custom board.

2) Did you contact IBM? If yes, what did they say?

3) Did you try new PPC 4xx ethernet driver in linuxppc-2.4 tree
(bk://ppc.bkbits.net/linuxppc-2.4)?

Thanks,

Eugene
