bash# uname -a

Maybe I'm confused about what it really means to run an rt kernel, but 
I'm running FC5/CCRMA and this is what the install page reads...

========================================================
Installing the low latency kernel

Planet CCRMA provides versions of the Linux kernel with one crucial 
difference with the standard kernel, the inclusion of the realtime 
preemption patch by Ingo Molnar.

Planet CCRMA on Fedora Core 5 currently includes two kernels with 
slightly different configurations of the realtime preemption patch. The 
more conservative is configured as PREEMPT_DESKTOP, the more adventurous 
is configured as PREEMPT_RT. The latter will give you (if it works on 
your hardware) much better low latency performance. As usual what you 
get in terms of latency depends on the exact mix of hardware you are 
running on.
========================================================

I'm running the kernel configured as PREEMPT_RT.

I'll have to check with the CCRMA list and see if anyone has had 
problems with the rtirq script on their FC5/CCRMA systems with this kernel.

Bear with me... this is all new to me...

Do I understand that 'chkconfig' would be the command to disable 
cpuspeed? If so, would you suggest that I disable it for all runlevels?

This is the output of '/sbin/chkconfig --list cpuspeed'...
cpuspeed 0:off 1:on 2:on 3:on 4:on 5:on 6:off

So... '/sbin/chkconfig --level 12345 cpuspeed off' would disable it for 
all runlevels?
