Right...it looks like the dm9000 driver uses some sort of pre-net/eth.c
interface which doesn't play well along with other drivers...

That would be great.

I think 1.3.4 should have the board_eth_init() stuff in place. Ben's
latest eth-initialization patches are probably worth a look too:

...though it looks like dm9000 is one of the "more complicated ones".
