I'd wonder if it's reached the point tha that the hardware is failing.  
At any rate, a generic realtek gigabit card (free after rebate!) will 
run rings around what was a good card in the late 90s but functionally 
obsolete today.

Back to the original config: did you know you could add the built-in 
adapter to the bridge, give your IP address to the bridge rather than 
directly to the built-in interface, and use the VMs the same way you are 
now without a second NIC?
