Virtualbox module needs recompiling after every reboot

Karmic would give me the message:

Kernel driver not installed (rc=-1908 )

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Re-setup the kernel module by executing

'/etc/init.d/vboxdrv setup'

Every time a virtualbox was initialised after rebooting. This would require the command given to be run with sudo privileges every single time, a lengthy and irritating wait.

This can be simply solved by adding the line "vboxdrv" to /etc/modules

So, in the terminal:

sudo gedit /etc/modules

Copy paste "vboxdrv" (without quotes) onto a line at the bottom of the file
Save and exit

Voila, hopefully problem solved!
