Yes, I had that too.  The Problem is that the XServe G5 actually has two
sungem MAC's in the chipset but doesn't use them (and apparently their
interrupt lines are not connected either).  Apple just doesn't put them
in their OF tree, but on the PCI they are visible.

The ethernet chips actually used and connected to the ethernet sockets
on the back side are th3.

Just don't compile (or load) the sungem driver on those boxes.

yes.
