Yes, that one worked, but... if I recall right, it didn't work in the
mainline version. Or more precisely, the mainline kernel didn't work on
N800 at all (at least for me).

When I did the porting (and if my memory works right) I had a big pile
of N800 patches on top of the mainline to get the board booting. And on
top of that, I made the new blizzard driver.

In fact, I possibly have the branch which I used in my backup
repository. I pushed it to:

git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git work/n800-39

However, looking at the log, it doesn't contain anything else than DSS
patches. So... Maybe that branch itself doesn't boot, it just contains
all the DSS related patches. I don't see any other related branches.
