booting from ext2 formatted SD card

[Sameer Verma]

Is it possible to boot an XO from an SD card with an Ext2 filesystem?
This is an XO with a dev key. I've followed instructions from
http://wiki.laptop.org/go/Ubuntu_On_OLPC_XO but it sits at the OFW
prompt saying "Unrecognized program format"

Any pointers would be great.
