Have you tried compiling the MTD, MTD_NAND, MTD_NAND_DISKONCHIP
 parts into the kernel rather than as modules?

If you do that, what kind of dmesg output do you get related to MTD?

my device nodes look like this:
bash-3.00# ls /dev/nftla* -al
brw-r--r--  1 root root 93, 0 Mar  4  2005 /dev/nftla
brw-r--r--  1 root root 93, 1 Mar  4  2005 /dev/nftla1
brw-r--r--  1 root root 93, 2 Mar  4  2005 /dev/nftla2
brw-r--r--  1 root root 93, 3 Mar  4  2005 /dev/nftla3

I never had any success with 32M, but 8M, 16M, 64M worked for me.
(48M worked, but had incredibly slow boot time.)

Does your process work with other sizes of DiskOnChip 2000?
