I forgot to add--I'm also on Gentoo but I believe Daryl is on Mythbuntu and
doesn't compile his own kernel, so it's probably not as simple as that for
him. Especially when it comes to eventual system upgrades which will likely
restore the removed driver... I think a more durable solution is required.
