I have been using a motherboard with a DOC 2000. I can boot from the 
diskOnChip and see it as a disk device with a ext2 filesystem using 
2.2.18 + Msystem patch + own cooked lilo patch...

Now I upgraded the system to a stock 2.4.6 kernel *with devfs enabled*

When I boot, I see the follwing message :

M-Systems DiskOnChip driver. (C) 1999 Machine Vision Holdings, Inc.
DiskOnChip 2000 found at address 0xD8000
Flash chip found: Manufacturer ID: 98, Chip ID: 73 (Toshiba TH58V128DC)

devfs: devfs_register(part1): NULL ops, got c02d8850 from major tableL


In /dev/nflt/disc0 I have two devices

/dev/nftl# ls
disc0
albator:/dev/nftl# cd disc0
albator:/dev/nftl/disc0# ls -l
total 0
brw-------    1 root     root      93,   0 Jan  1  1970 disc
brw-------    1 root     root      93,   1 Jan  1  1970 part1

No other things.

NB : /dev/discs/disc1# ls -l
total 0
brw-------    1 root     root      93,   0 Jan  1  1970 disc
brw-------    1 root     root      93,   1 Jan  1  1970 part1

But I can not mount the filesystem. The filesystem is valid as it works
with the 2.2.18 kernel...

Any idea?
