The USB driver should work fine, I have an Efika (MPC5200B) with that
exact USB controller and revision and it's just fine and dandy. We also
used to ship Via-based USB cards in the Pegasos Open Desktop Workstation
(using Marvell Discovery II northbridge).
The major difference here would be that PCI tree entries were created
by a real OF implementation so may have reflected some hardware better;
it is dynamically created on boot to a certain point, rather than a fixed
device tree which may contain some "errors". There seems to be a lot less
data in our tree...
I can't vouch for the correctness of your tree, though, or tell you
what might be wrong (looks fine as far as I am concerned, but what
do I know? :)
