[Beowulf] Keeping the Athlon MP cluster limping along

Hrm, I'm unsure, many motherboards like the MSI Neo line mention ECC as
"compatible" but I'm not sure that means that the ECC functionality
is enabled.

The north bridge is onchip and does support ECC:

Where it mentions:
	72-bit DDR SDRAM memory (64-bit interface + 8-bit ECC)

I've yet to find a s939 or s754 motherboard that specifically mentions
compatibility with ECC as well as the functionality.  Some of the older
athlon xp motherboards pulled this trick.  In particular having BIOS
allow turning ECC on/off would be reassuring.
