Hi Mark,

Sorry to hear about your problem.  This does however sound like something with 
your system.  The device has been supported for a long time now in the e1000e 
driver.  I think you still have something going on with your BIOS that isn't 
setting things up correctly regarding the LAN device enablement.  

Have you tried to update the BIOS on the system?  Maybe that might set things 
up correctly once again.

Sorry but I really don't think this is a driver issue.

Cheers,
John
