ignore it, p4-clockmod is a waste of bits anyway.

                  ^^^^^
This is a sign your BIOS has no idea what that CPU is. It should be a nice
non-numeric name.

Which could explain why VTX isn't showing up.  (Possibly also EST too, which
would be much better than using p4-clockmod).

Look for a BIOS update.
