That's not correct.

That's because without a page table the BDI2000 defaults to 1:1 translation.
By clearing the location above you told the BDI2000 that no page tables
are available.

No, you don't. Just use a newer kernel that has this feature available for
all processors. You could also copy the couple of lines of code from a
newer kernel into your 2.4.4 if you insist.
Thanks.
