Can a Dell® PowerEdge® SC420 be upgraded with Cedar Mill Pentium® 4 processors?

Until Steve Ketchem sent me a screenshot showing a '631 running in a SC420 (I blurred details that named the machine, etc., or that I thought might otherwise leak information), it seemed very, very unlikely indeed: there is only one report online of a SC420 being upgraded with a '631 and the preponderance of evidence suggested otherwise. It appeared that the Intel® E7221 northbridge used in the SC420 simply doesn't support the Cedar Mill processors, making BIOS support a moot point, but Steve's email complicates the picture.
