What are you using to measure latency?

Where does the realTimeConfigQuickScan toll come from? I would have to 
look at it to see how it figures out if a kernel is rt patched or not. 
It is very likely the program or script is old and is not using the new 
configuration option name for rt in 3.x (CONFIG_PREEMPT_RT_FULL).

The kernel does include the rt33 patch.
