Disable interrupts durring the lock step frequency/voltage change. Generic
IPIs are handled without blocking interrupts. This solves the random lockups
people have been seeing with apmd -C, thanks to marco@ for showing me how

affecting his Athlon64 machine so I stopped chasing bugs in est.
ok oga@, weingart@
