If you boot with an 'smp' kernel, support for multiple CPUs is automatic. If you do a clean Fedora install on a dual-CPU box, an smp-kernel should be automatically installed and set as the default. If not, you can always install the rpm yourself.
[bevan@urd ~]> rpm -qa | grep kernel
kernel-utils-2.4-9.1.101.fedora
kernel-smp-2.4.22-1.2129.nptl
kernel-2.4.22-1.2129.nptl


(I know I need to update it again...)

Hyperthreading is generally configured at the BIOS level, with nothing more to be done at the kernel level. If it's turned on in BIOS it will seem as though you have -4- processors (two virtual processors per real physical processor).
