angstrom / narcissus+ 6440, how to get it running?

Remco
any of you managed to get narcissus running on a 6440?

i am using the standard linux sd loader to get a yaffs image onto the
flash.

first try was to have narcissus make me a tgz, and convert it into a yaffs
image with mkyaffs2image. extracted the kernel image seperatly, and copied
to sd card. the sd loader copied the yaffs image to flash just fine, but
the kernel refuses to mount it:
VFS: Cannot open root device "mtdblock2" or unknown-block(0,0)
Please append a correct "root=" boot option; here are the available
partitions:
S3C NAND Driver, (c) 2008 Samsung Electronics
S3C NAND Driver is using hardware ECC.
NAND device: Manufacturer ID: 0xec, Chip ID: 0xda (Samsung NAND 256MiB 3,3V
8-bit)
Creating 3 MTD partitions on "NAND 256MiB 3,3V 8-bit":
0x00000000-0x00080000 : "Bootloader"

0x00580000-0x10000000 : "File System"

1f00             512 mtdblock0 (driver?)
1f01            5120 mtdblock1 (driver?)
1f02          256512 mtdblock2 (driver?)
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(0,0)

2nd attempt: if i ask the narcissus generator to make me a yaffs2 file, the
friendlyarm loader refuses to copy the image.

Anyone any pointers on how to get a basic image running?

Thanks,
Remco

oh, forgot a piece: 
its like this:
-- lots of non-related stuff --
VFS: Cannot open root device "mtdblock2" or unknown-block(31,2)
Please append a correct "root=" boot option; here are the available
partitions:
1f00             512 mtdblock0 (driver?)

Don't see the option for YAFFS2, however . . .

I did give it a go about 6 months ago and the issue I had then probably is
still relevant.  The only kernel that has all the fixes for this platform
is the one on buserror's site.  Although there are probably a few other
kernels around that are possibly patched properly.  

Have a look here:
http://mini2440.netyxia.net/viewforum.php?f=4 

And open-nandra has patches for 2.6.37-rc1, which I need to try compiling
with the standard config_mini2440_N35 in the FriendlyArm distro.

Good luck.
