How you can extract it?
# make sure sdcard is mounted
dd if=/dev/block/nandc of=/sdcard/boot.img

And if you wanna make sure, you could use a Linux box and see if you could splitt the image, I use split_bootimg.pl

Writing boot.img-kernel ... complete.
Writing boot.img-ramdisk.gz ... complete.
Then you proberly got the right image
So you shold look for partions on your device that is about 20 Mb
