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).
