[Beowulf] Badness in Shanghai upgrade

[Greg Lindahl]

I had been planning for a long time to upgrade a bunch of my AMD
dual-core systems to quad-cores when quad-cores were cheap enough --
same socket, no problem, right?

Well, the motherboard that I have apparently doesn't supply quite
enough power to the memory when it's being driven by a Shanghai
quad-core cpu.  My test machine panics once per 2-3 days. I have a
couple of Barcelonas and they work fine with this same mobo.

Ooopsie. Good thing I don't own that many of 'em.
