This is perfectly possible. I'm runing everyday Chinook and 'clean' test 
install of Diablo. Kernel and initfs is from Diablo.

I don't see anything wrong, few random hints

- extract rootfs.jffs2 from .bin again and never mount it rw on desktop 
i.e. do 'mount -t jffs2 -o ro /tmp/mtdblock0 /tmp/jffs2' on PC. I've 
seen corruption of the image if mounted rw on PC.

- use tar instead of rsync (should not make much difference)

- performance tip - mount destination ext2 with noatime, run rsync with 
--inplace to prevent creating 2x more files in destination (one 
temporary, one real)
