Thanks.  I may get time to try to reproduce the problem, but if I can
confirm it then I'll probably remove the "olpc-update debian" build and
the Wiki page if nobody will step up to maintain it.  I don't like the
idea of people stumbling on things that are now broken.

There are active maintainers.

OLPC has no plans to provide Debian on XO that I'm aware of.

I've not heard whether Debian plans to provide Debian on XO.

DebXO contains several changes to compensate for change to the XO
firmware since "olpc-update debian" was created.

I don't know any off-hand.

I don't have this available yet.

I recall a mention of it, yes.   I don't recall who did that, but the
reasons were rather special and unlikely to be portable to general

If you'd like to explore the initrd's of the various builds around the
2006 and 2007 timeframe, you might find how it was used.  I don't know
what is used at the moment for the F11 builds.
