cannot blacklist bluetooth

This is probably not the right package (module-init-tools) as I'm guessing something else is loading this module in some inappropriate way.

$ lsmod | grep blue
bluetooth 166112 23 rfcomm,bnep,btusb

$ cat /etc/modprobe.d/smoser-blacklist-bluetooth.conf
# smoser blacklist bluetooth
blacklist bluetooth
$ ls -l /etc/modprobe.d/smoser-blacklist-bluetooth.conf
-rw-r--r-- 1 root root 49 2011-10-31 16:59 /etc/modprobe.d/smoser-blacklist-bluetooth.conf

$ uname -r
3.0.0-12-generic

$ lsinitramfs /boot/initrd.img-$(uname -r) | grep blue || echo "nothing"
nothing

I've rebooted since adding that file above.
