Yes, but debian can also run on XO.
However I found http://wiki.laptop.org/go/Ubuntu_On_OLPC_XO not good
because it puts the fedora kernel on the ubuntu which works with some
discrepencies ; it takes also some time because of qemu and the boot is
not optimal.
Today, the stuff with debian on XO is cleaner and very fast to install
and test ; http://wiki.laptop.org/go/DebXO is the best page I found
about it :
 # zcat debxo-$DESKTOP.ext3.img.gz > /dev/sdX  (for instance, sdb; not sdb1)
And update the firmware to q2e34.rom at http://dev.laptop.org/pub/firmware/
Then it works fine either on SD card or USB pendrive of 2 GB minimum and
you can still boot and use the native fedora XO build.
With SD cards you could need some swap that can be made with a file
/swap.bin as explained at
http://www.olpcnews.com/forum/index.php?topic=4053.0
However, I have to compile a more recent kernel because the 2.6.25
version on that debian lenny is not sufficient for some of my experiments.
With all the wiki documentation pages I don't know on which I should write.

Aimé
