Off hand, i can't point you to a link. But this kind of stuff has definitely been done. i recall watching a talk (most likely on youtube) with Tannenbuam discussing this very idea (of using drivers to cause havoc on purpose, in order to test the microkernel). If i remember correctly, they never were able to make the microkernel/system crash, only the driver, itself. That is one of the points of microkernels, so naturally, it would only be logical to do real-world testing of the design.
