[Olpc-open] debxo 0.2 release

[John Watlington]

Trying to installing either the gnome or awesome JFFS2 versions from
an SD card formatted as ext2.

Using laptop firmware q2e18, on two different machines, this fails with:
<....>:75: error writing to NAND Flash
after writing 40 blocks.

What is going on ?
