well, software PWM depends on the main CPU and wastes precious cycles.
Besides, I'd like this to work for standard beeps, e.g. BIOS POST
beeps and similar stuff. And I need an amplifier anyway (because I
want higher maximum volume), but I might not want BIOS POST beeps and
standard beeps to sound at max volume the whole time.

And I'm not too sure if the software PWM driver will get along with
the CPU on-the-fly speed changing (cpufreq powernow-k8)
