Dave,
Thanks! This was the case with the dmfe driver on SPARC.
I've attached a patch as comment #6 on:
	http://bugzilla.kernel.org/show_bug.cgi?id‘06

User confirmed dmfe driver (with patch) finds the MAC addresses.
I'll ask Kyle McMartin to push this.

Unfortunately, the device still doesn't work.
Any SPARC volunteers interested in working on this bug?

I don't have the HW or interest to work on this further.
It's possible recent changes to dmfe might have also fixed some
of the issues (IIRC, phy reset patch was pushed in Decemeber).
I'd be happy to advise/review changes for anyone who works on it.

thanks,
grant
