Yes, that's all you need.  Just add that line, rebuild and reinstall the
kernel, and you're all set.  Works great.  Hyperthreading doesn't buy
you as much as truly separate processors, but it helps you get more bang
for the buck out of your single processor (depending on the type of
workload you run).
