Doh!

Turns out to be a hardware problem - when checking the jumpers I 
discovered a transistor on the MB next to the failed nic that is too hot 
to touch - new MB is on the way from Silicon Mechanics (who by the way 
are great to deal with)

With hardware today I see so few dead components that I stopped checking 
the obvious first.
