Running kernel version vs. kernel source version

Hi All, I'm just about to test the latest autofs (4.1.1) and hence need to recompile the kernel to apply a patch... I'm running k_deflt-2.4.20-105, but the source claims to be kernel-source-2.4.20.SuSE-104. Is this right? Also, I'd prefer (for obvious reasons) to test the new kernel but keep the current one. Obviously I can rename the new kernel image before copying it to /boot, and set up a new grub entry. But how can I go about having two copies of autofs4.o and two sets of support programs?
