trouble with a 16MB DOC Millenium

[Jesse Malone]

I've been trying to get a DOC Millenium working with a 2.6.23 kernel with
the mtd drivers compiled into the kernel. The NFTL driver is not happy.
After formatting with the dos utility from M-Sys I get this output from
the nftl driver:

I ran nftl_format on /dev/mtd0, which appears to have done some good. I
think I may have access to the nftla1 device, though its not mounted and
its giving me errors about media headers dissagreeing. Here's the output
after doing the nftl_format:

I'd like to see if I can partition it, but the warning about media headers
dissagreeing concerns me. Any advice would be very much appreciated.

Just to provide a bit more info, here's the output from the M-Sys DINFO
utility(before I did nftl_format):
