did you know you can disable this at boot time?  Check it out:

| $ grep mce /usr/src/linux/Documentation/kernel- parameters.txt
|       mce             [IA-32] Machine Check Exception
|       nomce           [IA-32] Machine Check Exception

just add 'nomce' to your kernel boot line in grub and you should be able
to boot with MCE turned of to reconfigure.
