I would like to run a command (that turns off bluetooth devices) at every startup. I normally use cron for these, but this is a command that needs to be ran as root. How do I do this?

4If you don't want bluetooth, why don't you just disable the bluetooth service?– GarrettNov 18, 2011 at 20:07

You can still use cron to do it.
make an entry in /etc/crontab like this
@reboot root /path/to/your/command
or as root type
crontab -e
and make an etry like:
@reboot /path/to/your/command
The /etc/crontab is the global crontab and thus you need to specify the user, crontab -e invokes the per-user crontab.
As you are already using cron, you can use @reboot as the time specification for a cron entry. On Debian/Ubuntu, the entry could be in a file in the /etc/cron.d directory.
I use the blueman tools to configure Bluetooth services. Configuration should be sticky.
If you want to completely disable Bluetooth, you should consider using systemctl to disable and stop the Bluetooth and blueman-mechanism services. Disabling will prevent starting the services on reboot, and stopping will kill any currently running services.
Original/Obsolete: You could try putting the commands in /etc/rc.local. Commands in this file should be run at the end of the boot sequence.
Disabling the drivers, and or software as has been described by @skrewler is often a good solution.

You're looking to modify your init.d scripts / setting. This can get complex and depends on your distro. You might be able to edit or create /etc/init/bluetooth.conf or /etc/defaults/bluetooth. But I think Vixie Cron supports cron jobs for root and has a start up time setting.
If you are on Fedora run this chkconfig --level 12345 bluetooth off
