I am also having the same problem with a MCF52236 board.
In short the LINK light will not come on.
Anyone seen this?
I just found out that there is an "A" suffix part that has this problem fixed.
I am waiting for samples...
Well the new part does fix 10/100MB, but it fails with 1GB switches (tested with LinkSys)
So I may need to do manual switching after all
