Re: 2.6.12->2.6.13-rc6 SMT changes -- intentional?

Just booted a box on 2.6.13-rc6, and noticed that it now only reports
a single processor, whereas on 2.6.12.4 it reports two.  While there
is only one physical processor, I wonder if this change was intentional,
since I can't find anything in the changelog about SMT changes.

Below is dmesg output from each kernel.

It looks like that ACPI is gone...  Can you recheck your .config that
you still have ACPI enabled?
