Which is (although there is a smiley) not a joke. Hardware drivers belong to the kernel, which is deemed "trusted" in models like grsecurity, and anything doing direct hardware access circumventing the kernel is deemed to be evil. So it does not target flashrom in special, but it is meant in fact for (or more likely against) programs "like flashrom". I would not be surprised if grsecurity also prevents r/w mapping of the BIOS chip.
