Hi Daniel. I can't say that I can help much, but there are couple of things 
you could check.

1. Did you follow the instructions for installing the low latency kernel?
apt-get install planetccrma-core-edge
or for dual processor machines, or with Pentium4 with hyperthreading enabled
apt-get install planetccrma-core-edge-smp

This package also installs a few additional packages, rtirq, and some Alsa 

2. Either with "synaptic" or running, rpm -q -a --last , as user. Check to see 
if along with ccrma kernel-2.6.12-0.21.rdt.rhfc4.ccrma, you have 

3. On the command line as root, open a text editor, gedit, kwrite or 
something, and go to /boot/grub/grub.conf . Remove the stuff at the end of 
the ccrma kernel line. Something like "rhgb quiet" . Dont remove anything 
else, only backspace as far as the "/". The line should now end with 
LABEL=/     Doing this will display all the text at bootup.

While you are in grub.conf,  put a # in front of the item "hiddenmenu" , which 
will bring up the grub menu at bootup.  Also increase the timeout to perhaps 
30 , which will give you a bit more time to make choices when Grubs menu is 
showing.  Now save, and close the editor.

btw. the default line is for which kernel to boot as default. "0" is for the 
first kernel on the list. "1" is for the second, etc.

All the best Nigel.
