also search talk.maemo.org for 'bootmenu'

You can either boot into clean system copy (mmc or flash) or you can log 
in over usb networking if you don't have full system to boot.

backing up whole rootfs as jffs2 image to mmc and restoring is possible 
too via mtd-utils commands (search t.m.o for mkfs.jffs2)
