I just posted two patches to linuxppc-dev that fix these problems.   
The message
are titled:

[PATCH] Update ucc_geth.c for new workqueue structure
[PATCH] Fix phy_read/write redefinition errors in ucc_geth_phy.c

I've tested these on an 8360EMDS, and Kumar has reviewed and signed  
off on the
code, so I think they're good.  Please let me know if they're not.

You should really copy Jeff Garzik and the netdev list on these patches.
