I have an IBM server with a single P4-3.06ghz chip that supports HTT.

Anyone out there have any tips on configuring this and if it works Ok?

I uncommented out the SMP section and built a kernel and rebooted.
I am online with only a few things in dmesg:

..I am unsure of the "PSE disabled" thing and the APIC_IO issues

Can someone kindly comment on this?

Reports that say something hasn't happened are always interesting to me,
because as we know, there are known knowns; there are things we know we 

We also know there are known unknowns; that is to say we know there are some
things we do not know. But there are also unknown unknowns -
the ones we don't know we don't know.
