  Log:
  Even though BIOS writer's guide recommends cpuid instruction of Cyrix
  6x86MX CPU is enabled (BIOS should not disable it), some BIOS disables
  it via CCR4.  In this case, cpu variable becomes CPU_486 and
  identblue() is called.  Because Cyrix 6x86MX has MSR and doesn't have
  MSR1002, wrmsr instruction generates general protection fault.
