    Yes exactly. I used to have a system with one P3 supporting FXSAVE
    and other not :-) I had to fix the kernel back then to support this.
    The system worked perfectly fine after the kernel was fixed.

    So the check proposed is a bad idea. It would trigger
    on real boxes which don't have any obvious problems.
