You don't want to use that yet :-) Use the 2_4_devel kernel.

The mmu always translates correctly, your programming of it
is probably incorrect :-)

What BAT did you change, and to what?

So, you did 'virt = ioremap(0xfdf40000)' and virt == 0xfdfd0000?
Where did you call ioremap()? Are you trying to remap the EUMB registers
