Since my last kernel update the driver e1000e was not blacklist anymore. I am not sure if it is the final solution. This is the bug fix solution (from kernel.org):
Set the hardware to ignore all write/erase cycles to the GbE region in the ICHx NVM. This feature can be disabled by the WriteProtectNVM module parameter (enabled by default) only after a hardware reset, but the machine must be power cycled before trying to enable writes.
Although the e1000e was unblacklisted I had to modprobe it again to work on my Ubuntu Intrepid. On a terminal:
sudo modprobe e1000e
