Actually, I've been thinking about adding a "mem=probe" command line type function, that would enable a probe routine. I've been too lazy to do it myself, though (hint hint).
A "mem=probe" should work on _most_ machines. But the number of machines it wouldn't work on is probably significant enough that we definitely do _not_ want that particular feature to be on by default.
