Quite a few. You can make the driver upload be done via a userspace app so its
pretty clearly seperate from the kernel.

As to the security risk - yes if you run a military installation or something
that is similarly paranoid. However its no different to the firmware burned into
ROM or the BIOS having NSAkey like hooks.
