What do these log messages mean?

[David Fox]

When I modprobe docprobe I get the following in syslog:

kernel: M-Systems DiskOnChip driver. (C) 1999 Machine Vision Holdings Inc.
kernel: Cannot find driver for DiskOnChip 2000 at 0xD6000
kernel: Possible DiskOnChip with unknown ChipID 50 found at 0xdc000

That's all I see.  Any ideas what I should do next?  The machine is
based on a Nat Semi board, essentially the same as a VirginConnect.
The flash device is marked DiskOnChip 2000, MD2200-D48.  I see that
the normal DOC 2000 chip ID is 0x20, should I patch the code to accept
0x50 as well?  Is it perhaps being fooled into thinking it sees a
DOC2000 at 0xdc000, and the real device is further down the list?
And what's going on at 0xd6000?

The 'Possible DiskOnChip with unknown ChipID 50' is just because there's no 
sensible way to probe for the hardware. Ignore it.

The real problem is "Cannot find driver for...".

Make sure you have CONFIG_MODVERSIONS turned off, and that you have 
doc2000.o loaded before you load docprobe.o
