You do not need a different kernel, but you do need the 'vmlinux' file from that RPM if you want to do kernel profiling, so oprofile can look up symbols.

Good question. I don’t know. Good question.

I.e. no way to run anywhere in production? I just quickly checked docs and it says that 2.4 kernels require source and 2.6 doesn't require even that. So why debug kernel? debug kernel?
