As I started this thread, I shall now close it (I hope).

The solution to my above system locking up was to disable the on-board 
bge NIC via the BIOS, and plug in a dual intel NIC that uses the em 
driver.  Also, ensure you have at least a Rev C board; mine is a Rev E.

Stable 10 days now under same load that would cause network failures 
and potential system lockups daily.

I have no idea if this is due to the driver for bge being buggy, or if 
plugging in the intel NIC changed some electrical properties of the 
system to stabilize it.

Hope this note helps someone else save a *lot* of time figuring it out.
