With the patch the FADS should work with or without MDIO support.
At least my FADS (with an 855T) does.

This was discussed on the ppcboot-users list last month, but
my attachments apparently didn't survive in the archives
on geocrawler, so I am posting them here again. The patches
are for the Denx linux-2.4.4-2001-07-23 kernel.

from my post on Ppcboot-users (11-Sep-01):
