loop-aes-utils, smbfs and Ubuntu

The following was experienced on Ubuntu Desktop 9.10

if you install loop-aes-utils, and then install smbfs, the cryptoloop.ko is removed from the kernel.

`mount` will give you errors like:

ioctl: LOOP_SET_STATUS: Invalid argument, requested cipher or key length (256 bits) not supported by kernel


`modprobe loop` will give you:

FATAL: Module loop not found


well, not sure what the whole story is, but the following fixes it.

`modprobe cryptoloop`
