This is what I'd like to be able to do... that way the checks that ioctl()
performs can be avoided.

However, there are problems with doing this:

(1) There's currently no definitive way to grab an unused syscall, whether a
random one or a pre-determined one.

(2) The syscall table is not exported...

(3) Even if it was... just filling in the syscall slot from a module means
that it is possible for the module to be unloaded whilst the syscall is in
use.
