The below fixes a reference counting bug exposed by commit 725522b5453dd680412f2b6463a988e4fd148757. If driver.mod_name exists, we take a reference in module_add_driver(), and never release it. Undo that reference in module_remove_driver(). My box now boots fine, and modprobe/rmmod didn't explode, so I'll add a blame line.

CONFIG_SYSFS_DEPRECIATED is set to Y here too, so I might have another problem here.. let's see what bisecting will show up.. seems to be a "wrong" alarm here, it was caused by a new xorg.conf and an intel 855gm chipset.
