 Just noticed that there wasn't a ticket tracking the noise made when Linux
 is booted on an XO-1.75 B1.

 Using any recent firmware and Linux build (say Q4B09 and OS6) there is a
 nasty squawk emitted by the speakers when the Linux kernel is booted.

 I'm assigning this to OFW as I remember Mitch saying he knew why this
 happened, and how to eliminate it.
