Having just been through this ... yes.

Recompile with SMP support and enable the Hyperthreading in BIOS if it's not already. The 2.4.21 kernel will be ok. You'll be able to then see both processors in /proc/cpuinfo

If you want to see both processors in top, you'll need to recompile the package that provides it from source.

I have a small question - I purchased a new machine on the weekend, P4 3ghz with HT. Do I need to update my kernel to an SMP one to gain the use of hyper-threading?
