I don't think we have a good definition of "removable media".

Also, you usually can remove a normally non-removable disk while hibernated,
so I just don't see why we should disable it in any case.

That said, it is reasonable to expect live CDs not to configure the system to
hibernate in response to overheating etc.  But that's not a problem we can
address in the kernel.
