TLDR; it won't work. coreboot needs to be adapted to every mainboard,
and, in this case, even to the processor and chipset. Without docu-
mentation from Intel (that we don't have), it might take an experienced
coreboot developer 1 or 2 years to support this processor.

Xeon 5400 and 5500 are very different. The older one still used FSB
and had the memory controller (two channel DDR2, I guess) in the north-
bridge, the newer uses QPI and has the memory controller integrated
(three channel DDR3, a much different beast). There is still not a
single platform with QPI supported in coreboot and the memory control-
ler is likely not close to any supported one either.

No, it doesn't.

Not sure, what your question is. You can use a different (supported)
motherboard. But not with this CPU.
