A kernel with this these patches load the e1000e driver fine on
a test machine which has a OK NVM checksum.

But it freeze on one machine which has a wrong checksum.

On this machine the NVM seems to be OK, but the NVM valid bit
is cleared. If I would set this bit, the NVM checksum would be OK
again. This is the T61 notebook which did show this error after
openSUSE 11.1 Beta1 install after a reboot during X setup.
