This one foxed me for a while, but came down to using a kernel that has
ACPI enabled.

I forget now if the transition was between 2.4.20 and 2.4.21, or 2.4.21
and 2.4.22, but the kernel changed so that you needed to enable ACPI
support for the logical processors to be recognised and used.

Hope that helps....
