Excellent! How may I get this updated kernel? Is there anything akin
to the Fedora updates-testing repository where I could update from and
report results on using hrtimer with software that makes good use of
Also, would there be any kind of detrimental effect -- perhaps on
battery life -- from having this module loaded but not used?
Or some unexpected interference with a tickless kernel's use of timers?

True... I was just on a roll with getting all the rest of my favorite
dev and apps from fedora running. You're not supposed to rpm --force
either to stop a dependency cascade, but I did... but I now can
record and play music through qtractor, and various DSSI plug-in
synthesizers ( zynaddsubfx-dssi, xsynth-dssi, fluidsynth-dssi,
whysynth-dssi) that are equivalent too thousands of dollars of
hardware and software, using equally nonrecommended hacks to use
CCRMA's application repository http://nielsmayer.com/meego/ -- all on
a cheap costco netbook.
Of course now that I got all that working, I need a RT kernel too.
Speaking of things that might just not work -- what about the adding
the real time preemption patches (
https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO ) to meego such
as used with CCRMA's realtime kernel:
http://ccrma.stanford.edu/planetccrma/software/planetccrma.html , for example
Is there any interest in using meego for realtime use? What is the
current "strategy" for handling real time audio, video, networking,
and other device access in Meego?
Note that I'm an excited newbie meego user -- just to see how it
works IRL, I installed it on my Son's netbook to update moblin at the
beginning of the month, and now he can make music on it instead of
playing games (or so dad says in theory and in hope). I'm personally
more interested in seeing it run on something like
http://openpandora.org/ (or an equivalent Intel Atom CE4100 device)
for my own uses.... IMHO such lower-powered processors and multimedia
are an area where a realtime kernel would be especially useful. I'm
hoping Meego suports this "use case", or will soon.
