Changes and notes:
- sugar and sugar-toolkit rpms are at 0.92.4!
- abiword and libabiword are in, but may have been built without asio
(the network/collaboration side) -- please test collaboration!
- In kernel land...

Wow, this is quite impressive! You must be one of the first that have this
in a real distribution for ARM :)

Do you have any references like a git-commit or discussion on a
mailinglist for this? I'd like to match this with some other ARM
hardware (non/OLPC) issues I have seen.
I joined the OLPC mailinglists only a while ago, and I must say that I
am really impressed with the work all of you are doing! It really seems
that you make progress quickly. Congratulations with yet an other
release update :)
Cheers,
Niels

Using Yum:
The default yum config - which we include - points to the official
Fedora mirrors, and those don't really support unsupported
architectures like ARM. Surprise!
Of course it's in my list of things to fix. In the meantime, here's
what you can do
- edit /etc/yum.repos.d/fedora-update.repo -- look at the first
section, disable it (enabled=0)
- edit /etc/yum.repos.d/fedora.repo -- look at the first section,
disable gpg checks (gpgcheck=0), comment out the mirrorlist line, and
add
baseurl=http://arm.koji.fedoraproject.org/repos/dist-f14-build/latest/arm/
You're done! Note that it is a partial repo, and it only has the
packages at the F14 release time versions. Additionally, some packages
are missing or tagged wrong.
If you want a package that is missing, ping Peter to see if it'll be
available soon.
If you see a package or dependency bail out complaining about
python(abi)=2.6, let Peter know. The repo is just showing the wrong
package (and the right one is likely there).

I think ChromiumOS is using flattened trees, but we're also running Open
Firmware and have it stay resident to be called into.

Do you have any references like a git-commit or discussion on a
mailinglist for this? I'd like to match this with some other ARM
hardware (non/OLPC) issues I have seen.
There's a description of our problem at:
http://dev.laptop.org/git/olpc-kernel/commit/?h=arm-3.0&id=b8923ed080...
Thanks,

Ah, didn't know ChromiumOS used it too.
It may be that OpenFirmware makes it easier (as PPC gathered some
initial experience with FDT), it's very cool never the less!

Nice description! As it's mach-mmp dependent, it's unlikely that I can
apply this for mx51 based systems. The information in the git-commit is
clear and I'll try to investigate if 'sporadic hangs' could be caused
due to missing events. (Which sounds sane, as it might happen when
the system is under high load.)
Many thanks for your reply,
Niels
