673	Hi, Could this function generate a devd event, with pitch and duration, for implementing via a real audio device? --HPS

Thanks for taking a constructive approach to the heated discussion! I'm no expert in this part of kernel, so please treat my "Accepted" more as "Liked" rather than "Approved" :)

685	I am curios whether up to 50% variation of the duration due to C_PREL(1) will be too noticeable or even annoying. May be we should be more strict here.

684	Here should better be beeping = 1 now to not overflow. I don't see a point to expand beeping to spintime_t.

684	Yea, nobody has a beep more than 1s, but it really is a bool and has been logically back to 386BSD, even though bool didn't exist then :)...
685	Likely. I think C_PREL(4) or 5 is in order...
