Hmmm, the Ethernet is going to be em or igb, but the problem is that a new device ID might not be enough as often when new device IDs are added to em/igb they come along with other changes to support stuff specific to that device ID. Maybe try grabbing the sys/dev/e1000 directory from 8.2 and dropping that into your 8.0 tree? You could also just grab a tarball of the 8.2 kernel tree and stick that on a USB drive to copy it over to your laptop and then boot an 8.2 kernel (with the keyboard fix). -- John Baldwin
