Details to access the root filesystem, for Great Justice&tm;

Obtain the latest firmware from [OpenPandora Support|http://openpandora.org/index.php?option=com_content&view=article&id=199&Itemid=40&lang=en] and extract rootfs.img therefrom

Emerge sys-fs/mtd-utils

Compile modules:
* mtdchar (drivers -> memory technology devices)
* nandsim (drivers -> memory technology devices)
* ubi (drivers -> memory technology devices)
* ubifs (filesystems -> miscellaneous filesystems)

Load modules

* modprobe mtdchar
* modprobe nandsim first_id_byte=0x20 second_id_byte=0xac third_id_byte=0x00 fourth_id_byte=0x15 cache_file=~/nandsim.mtd
* modprobe ubi mtd=0
* modprobe ubifs

It'll probably be unformatted, so do this:
* ubidetach -p /dev/mtd0
* ubiformat /dev/mtd0
* ubiattach -p /dev/mtd0
* ubimkvol /dev/ubi0 -N rootfs -S 4052 # <- use number of available LEBs spit out by ubiattach
* ubiupdatevol /dev/ubi0_0 rootfs.img
* mount -t ubifs ubi0 /media/rootfs

See [http://www.linux-mtd.infradead.org/faq/nand.html#L_nand_bootloader] for some example ID bytes for nandsim
