In a related vein, was M-Sys's TruFFS being loaded at bootup? So far,
I've found no obvious problems that would keep it from working, but a
very odd problem.

I create a test file like this:
modprobe doc2000
modprobe docprobe
modprobe inftl vfat
mount /tmp/inftla1 /mnt
dd if=/dev/urandom of=/mnt/testing bs=1024 count=128
sync

If I unmount and rmmod modules, then reinsert and remount, everything is
happy:
umount /mnt
rmmod inftl vfat
modprobe inftl vfat
mount /tmp/inftla1 /mnt

The file testing will still be there.

If I reboot the system, it goes away. The best I can figure is something
in TruFFS does not like something we do, either in VFAT or INFTL.
