Sorry, the question on the end slipped out of my screen and my attention...
It is CONFIG_PREEMPT_RTB=y as you already figured out.

No, don't dissmiss this option. I am currently testing this stuff on an 
arm1136jfs with 533Mhz. The CONFIG_PREEMPT_RT _FULL with the softirqs is to
slow on this machine to handle a 9.6khz interrupts. I think mainly because 
of the additional context switch caused by the softirqs.

But going to CONFIG_PREEMPT_RTB we are right on the sweet spot for this 
machine. We observed worst case usermode latencies for 1.2khz and are 
able to handle 9.6khz hardirq with reasonable cpu load. So the 
CONFIG_PREEMPT_RTB is the right option for puny systems like arm1136.

Annotation: i was interrupted while writing this mail, so the below part
is outdated by other mails from you. (https://lkml.org/lkml/2011/8/11/139)

I just thought that that it might be some changes in 3.0.1 compared to 3.0
but i noticed that the rt8 patch also cleanly applys against 3.0 and i tested this
The butsplat looks very similar to my other bugreports sent today.
