That's not correct.
.... This works for kernel
debugging, but memory translation fails when I try to do dynamically loaded
module debugging.
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.
I guess I have to set PTE pointers for BDI2000.
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.
