I was surprised&happy to see "SMP

Seems like all that's missing between this solution and my "meegolem"
hack of adding Fedora RPMFusion and PlanetCCRMA app/lib/devel
repositories to Meego is the "RT" from the CCRMA realtime kernel? Or
is Meego 1.1 already fully realtime capable and the message just omits
"RT" ?
MeeGo's kernel is not PREEMPT_RT.
For several good reasons, MeeGo needs a 2.6.35 kernel, and there
currently is no -rt patch for that kernel.
At the moment, pro audio performance on MeeGo is bad because of CPU
frequency scaling. However, if you disable it[1] I'm getting good RT
performance from MeeGo.

[1] One way is to recompile the kernel with some different config options.
