	It is accurately showing how much a process is _directly_
	using memory. In my example there was 443M missing. My
	_guess_ was that it was mostly used by a disk cache, thus
	indirectly by processes, and as our driver is the only active
	process, I think it is reasonable to say that the driver uses
	most of the disk cache and then also most the "missing"
	memory.

	Even when there is no virtual RAM is not being used the extra
	RAM helps keep disk cache hit percentage high, in our case
	read cache hit percentage is 99%, write cache hit percentage
	is 92%. The "sar", "iostat" and "vmstat" utilities are your
	friends here!
