I don't see anything on "hyperthreading" re the Athlon XP.

I've been running dual P3s for a long time, but I'm seriously
considering whether SMP is worth it for my system (not a network
server) given that SMP severly limits the choice of motherboards for
an upgrade/update.

However I've geared my Mandrake 10 installation to the "Enterprise"
kernel, which is SMP, and would hate to have to reinstall it all.
