i find it mindboggling and rather sad that you are still in denial :-(

this is an obvious regression to me, with a very simple fix. No other 
PCI driver breaks like this. We've got three thousand Kconfig options - 
it is clearly not realistic for users to keep such details in mind to 
avoid pitfalls. E1000=y && E1000E=m is uncommon but can easily happen. 
E1000=y && E1000E=m simply makes no sense in light of the PCI ID 
stealing that occurs if E1000E is enabled.
