Got my mouse scroll wheel working. Just uncomment the following line in /etc/X11/xorg.conf:
As for the network card, it's still coming up dead on some bootups, but I discovered that it probably is a firmware issue. In my BIOS POST logs, there are regular occurrences of an NIC Failure. Will have to hunt around for firmware. It was suggested to me that power management might have something to do with it, but I didn't notice any related settings in the BIOS. Should probably double check that.
Option: "Protocol" "Auto"
