...

Is hyperthreading enabled on 2.6 and 2.4? Can you send
a cat /proc/cpuinfo | grep processor for a 2.4 and a 2.6
kernel please?

If you have hyperthreading enabled, try 2.6.7-rc1 with
SMT (hyperthreading) scheduler support enabled in the
kernel config. It is in processor type and features menu.
