Intel Atom N270 with ACPI on - OpenSuse 11.2

[utneflyte]

Hi all,
I’m using a purpose built computer with Intel Atom N270 CPU and running OpenSUSE 11.2 (Intel® 945GSE + ICH7-M chipset)

If I leave ACPI = Enabled in the BIOS Setup, then the Yast Hardware Profile shows 2 x N270 running at 800 MHz.

If I turn ACPI = Disabled in the BIOS Setup, then the Yast Hardware Profile shows 1 x N270 running at 1.60 GHz.

Anyone experienced this with their system?
Intel Atom N270 is a single core, so why is it seen as a dual core with ACPI on?
Based on the above, should I simply leave ACPI turned off?

Any insights greatly appreciated.
Cheers.

I would assume that this phenomena is connected to a virtual second processor:
Intel® Atom™ Processor N270 (512K Cache, 1.60 GHz, 533 MHz FSB](http://ark.intel.com/Product.aspx?id=36331)

But my hardware is not so new so maybe another on can affirm that…
