Actually I'm not using modules from initfs at all nor updating them but
I have compiled the ext2 in so that initfs can mount the ext2 formatted
root from mmc (flasher --set-root-device=mmc).

This device node update to initfs is required since Maemo 2.6.21
kernel & initfs are using major number 254 for mmcblk whereas newer
kernels are using 179.

I basically copied initfs from running system or fiasco image, I don't
remember, modified it on desktop and then created new jffs2 image out
of it. That can be then flashed with "flasher -f -n initfs.jffs2".

I think it would be possible to boot modified initfs also from another
mmc partition so that initfs on NAND can be intact.
