Maybe we should start a mailing list.

Are you using latest BDI2000 firmware?
I'm missing a PTBASE definition in this section - without it only
default translation is enabled. See the BDI2000 user's manual,
Section "3.2.2 Part [TARGET]" (Entries "MMU XLAT [kb]" and "PTBASE
addr") and Section "3.3.4 Embedded Linux MMU Support".
Please note that the 2.4.4 kernel on our FTP server does not yet
include the automatic update of the BDI page table information
structure mentioned in the BDI2000 manual. We will have this in the
next version (as soon as it's running stable).
