If they are not needed by any of the drivers you're aiming at, you should
probably just drop them.

What do you mean with overload Deref? What I mean is

	impl Deref for AcpiBuffer {
		type Target = [u8];

		[...]
	}

	impl Deref for AcpiInteger {
		type Target = u64;

		[...]
	}

	impl Deref for AcpiString {
		type Target = CStr;

		[...]
	}

etc.
