 From the source code, the driver is trying to read the media type 
setting from the eeprom and failing to get anything it understands.  
This looks like only the second bit of info that is looked at from the 
eeprom, and the first bit wouldn't give an error if it too was returning 
0x0.  This is just my quick reading of the code, though! I would 
definitely be starting to think that adding the memory triggered a 
hardware problem, perhaps static, or something physical.

Presumably you don't have another OS installed on the machine (<dread 
look> Windows or Linux) because if it too couldn't see the ethernet that 
would be a strong indicator of hardware problems.
