It might have something to do with the hardware indeed. I'm using a Dell
Latitude D610 and i get the same error when checking the APM parameters.
Even still the clicking stopped with -B 254, i haven't checked the
numbers yet so my mind could be playing tricks on me.

The current solution appears to be good and once the final configuration
is settled it should be put in to place. The problem is that we should
have a way to detect broken hardware and notify the user about the
possible problem. Once this solution is labeled as working most of us
will continue working without any more thought about the issue while the
hardware could still be subjected to excess stress.
