I've quickly ported the patch stack to 2.6.24-rc5-rt1, and it doesn't
really work:

----------8<----------
root@phyCORE-MPC5200B-tiny:~ cyclictest -n -p80 -t1 -i10000 -l 1000
0.44 0.35 0.15 1/44 483

T: 0 (  483) P:80 I:   10000 C:     992 Min: -490034 Act: -410032 Avg: -243020 Max:     -10
----------8<----------

Even on an idle system I get negative values and a "running" Act value.

I'll have to clean up the patch stack and check what's going on.
