The problem seems to have gone away of its own volition (it wasn't even soon after i did an upgrade, I just thought I'd try again), so I'm closing this bug. Interestingly, sudo nvidia-glx-config enable did nothing, telling me that the nvidia driver couldn't be found, but changing my xorg.conf manually worked perfectly.
