PAE and DAHDI Help

I am looking for instructions on moving to the PAE kernel. I have the kernel-PAE and kernel-PAE-devel packages installed, but had a problem with DAHDI on reboot. What is the proper way to install the correct DAHDI packages for the PAE kernel? A step-by-step would be great, as this is a production problem/server and the cutover needs to be quick. Long term, we will go 64-bit, but it is still in beta ATM.

Much, much appreciated,

After looking around the web more, it looks like I just need:

yum install kmod-dahdi-linux-PAE

Is there anything else? I want to make sure I am prepared enough for the move.
