Ok. It works.

I found this in dmesg:

BUG: swapper:0 task might have lost a preemption check!
Pid: 0, comm: swapper Not tainted 2.6.24-rc7-rt2 #3

This is really really strange. cpu_idle calls __preempt_enable_no_resched
and not preempt_enable_no_resched (notice the prefixed underscores).
So I don't know how you got that output. Did you get any strance rejects
in applying this patch?
