HowTo Re-compile RHEL 4 Kernel

[Reuben D. Budiardja]

Hello,
Does anyone know if there's a step by step HowTo for recompiling kernel that 
shipped with RHEL 4 (kernel-2.6.9) ? 

I've tried searching the site redhat.com and docs but haven't found anything. 
The last time I compile a kernel manually is a while so my skill is very 
rusty. Basically what I want is to use the shipped kernel .config, except to 
change (enable) one or two options that were not included in the shipped 
kernel.
I am not worry about support as my copy of RHEL is academic license, and this 
is just for testing purposes (ie. play around with my own desktop).

Thanks for any help and/or pointer.
