Compatibility between m-system and mtd-driver

Hi folks,

I have a x86-board with a DOC-millenium. The DOC contains a single partition 
with a ext2-fs which is intented to be the rootfs. The partition was created 
and populated using the m-system driver v4.2.
When I use a kernel 2.4.9 with included mtd- and nftl-support, everything 
works fine. On boot up the kernel reports:

  M-Systems NAND Flash Translation Layer driver. (C) 1999 MVHI
  $Id: nftlcore.c,v 1.73 2001/06/09 01:0943 dwmw2 Exp $
  Partition Check:
   nftla: nftla1
  VFS: Mounted root (ext2 Filesystem) readonly.
 init started: Busybox v0.51.....

When I use the latest mtd-code from CVS and try to do the same, I get this:

  NFTL driver: nftlcore.c $Revision: 1.85 $, nftlmount.c $Revision: 1.25 $ 
  NFTL_notify_add for DiskOnChip Millennium 
   nftla: nftla1
  VFS: Mounted root (ext2 filesystem) readonly.
  Freeing unused kernel memory: 48k freed
  Kernel panic: No init found.  Try passing init= option to kernel.
...and it's definitely not a problem with the init. The kernel seems to mount 
the filesystem but has problem to read it correctly. 
There is something which makes it confusing. When I use a harddrive to mount 
the rootfs and try to mount and read the DOC-partition later, I don't see any 

Any comments ?
