I've attached a copy of my bootlog.  I added in one patch to enable
rgmii but that didn't fix
it.(http://ozlabs.org/pipermail/linuxppc-dev/2007-October/043435.html)

I am curious why the new emac driver is enabled in the DENX tree but
not in the upstream trees.  Has DENX successfully used this driver on
the Sequoia board?  Am I trying something that is known not to work?

I'm interested in helping in whatever way I can.  I need ARCH=powerpc
to use the current Xenomai patches, and I need both EMACs so I can
evaluate bonding (for high-availability).

Have you tried adding the various patches I posted along with the
patches Valentine posted ?

I'll re-send a full serie later this week. Let us know if those help or
if something is still broken.

Cheers,
Ben.
