Looks like I'm in over my head.  I think a section for the 750 needs to be added, but I'm not sure what to add exactly, and I'm now afraid I'll light my computer on fire if I try.  The Intel doc with the specs is here:

and the doc for the already entered processors is here:

Is there and ACPI person out there than can whip up a patch that I can try?
