If you are running a Sandy Bridge laptop, there is probably a BIOS update
that might fix this.  I don't think Sandy Bridge processors have been
released to the general public yet.

We were chasing broken MCEs in Nehalem that reported bad memory all the
time.  Various kernel hacks worked around it until a BIOS fix came along.

I wouldn't be surprised if this is just another broken MCE, especially if
the laptop doesn't feel hot.

Cheers,
