autodetect dual CPU

[doublec16]

I'm installing RH8 and I'm wondering if it will automatically detect the 2 CPUs and make it use both automatically, or if I'll have to recompile the kernel after I install, to make it work. Quite a few months ago I had to compile the 2.4.18.rc2.ac3 (or something like that) kernel with SMP enabled to get both of the CPUs (Athlon 1700+) to be detected and used by linux. I notice that RH8 uses the 2.4.18 kernel without any rc2 or anything so I'm worried that I'll have to do it all again. I don't mind compiling kernels but it is rather time consuming and I always screw up a few times so that my sound quits working, or my network card isn't found, or a plethora of other catastrophes arises. Has anyone installed RH8 onto a dual CPU system and can tell me whether this will work for me? Thanks.

At least with my distro,

uname -a

shows SMP in the kernel name and in the date/time stamp.

cat /proc/cpuinfo (should also show both cpu's)
