Here is the lspci information, both -x and -vv.  This is with 
two of the e1000 single-port NICS side-by-side.  I have also 
strapped a P-IV CPU fan on top of the two cards to blow some 
air over them....running tests now to see if that actually 
helps anything.  If it does, I'll be sure to send you a picture :)

Ben, I checked the datasheet for the part shown in the lspci dump, and it
shows an operating temperature of 0-55 degrees C.  You said you measured 50
degrees C, so you're within the safe range.  Did the fans help?

The thermometer he used likely showed a much lower temperature than what was 
actually on the die. 5-10 C more are not unlikely. It's hard to measure chip
temperatures accurately without an on die thermal diode or special kit.
So I would expect that when an external normal thermometer showed 50C 
it was already operating out of spec.
