We should properly forward the CPUID format bit. CPU model detection on systems without IBC might select a model with a wrong CPU type (esp. selecting the business class (BC) model on an enterprise class (EC) machine). So let's improve that, too.
I am also preparing a patch to properly indicate the correct cpu type to the guest via STORE CPU ID and STORE HYPERVISOR INFORMATION for the TCG case, but will send that separately after I tested it (want to write a kvm-unit-test for STORE CPU ID).
