    James, you can erase BIOS flash from linux userland, you could probably
    even physically destroy it too. I can think of great ways of physically
    destroying one's CPU and maybe even motherboard too, from userland.

    This is nothing new.

    Is the kernel broken because you can bit-bang the hardware as root? Think
    about it.
