I'll have to give that a try. If I can find the pinouts and such for

Yoy! Is it not possible to set up some sort of watchdog timer instead?
watchdog() /* runs once a second */ {
if (in_driver) {
if (was_in_driver)
panic();
was_in_driver = 1;
}
}
naughty_driver_routine() {
in_driver = 1;
...the routine...
in_driver = was_in_driver = 0;
}
