Rebuilding binary kernel RPMs

Hi, if this isn't the right list, I apologize in advance, and perhaps you can point me in the right direction.

I'm trying to figure out how to get from a kernel-source.src.rpm anda k_smp.src.rpm to a k_smp.i586.rpm. I'm more familiar with how Red Hat does kernel builds, and I have not yet figured out the tricks for SuSE.

Some questions that come to mind...

How is the k_smp.src.rpm generated? How is it (and/or kernel-source.src.rpm) used to re-generate a binary k_smp.i586.rpm?

I'd like to make some changes to the stock SuSE kernel, and build & package it just as SuSE does, for installation on several machines. is this documented anywhere?

Thanks,

-Eric
