I'm curious about a little segment of the APM code:

in do_ioctl:

        if (!as->suser)
                return -EPERM;

This means that only root can issue to the ioctl to suspend the machine.
That seems odd, since it overrides the file permissions on the character
device. I don't like the idea that any APM-aware program has to be suid-root
to suspend the machine, I'd rather be able to select who can and can't 
twiddle with APM suspend using the permissions on /dev/apm_bios.
