I'm seeing the same thing here, on a similar machine ( 6459CTO ). I
pulled the source from kernel git last night to test it.

Subject: ACPI : Delete the IRQ operation in throttling controll via PTC
>From : Zhao Yakui <yakui.zhao@intel.com>
The IRQ operation(enable/disable) should be avoided when throttling is
controlled via PTC method. It is replaced by the migration of task.

I reproduced this issue on my T61, and saw it go away w/ this patch.
I'll be sending you a pull request probably Sunday night w/ this
