Wait. What now? You have (at least) two sound-devices that can beep:

a) the beeper on your motherboard

  in this case, use what I wrote, i.e.
    pcsp=enable=1
  in your kernel commandline and make sure
    modprobe pcspkr
  works. The module is not needed in the initrd.

b) the onboard-sound-chip via attached speakers/headphones

  in this case, disable the mobo-beeper (might be default)
    blacklist pcspkr
  explicitly, possibly along with with the kernel-parameter
    pcsp=enable=0
  and your normal alsa-driver should take over the task of "beeping"
  (snd-pcsp is a different beast).
  If it does not, your alsa-driver might be buggy as it should take
  over the beeping.

HTH,
-dnh, I wanted case a), beeping completely independent from any other
    audio stuff. And with the program 'beep'
    (http://www.johnath.com/beep) and/or the snd-pcsp driver, you can
    use the beeper to do more than the standard beep.
