I've considered doing that but have never convinced myself it's worth
the effort. Though the noise is particularly galling.

As I understand it the volume gets stored as an EFI variable, so I
always imagined that it would be possible to fix it from the efi shell,
if you knew what to change.
I generally picture doing this by finding someone with a similar macbook
and MacOS and convincing them to:
      * turn down the volume in Mac
      * reboot int rEFIt
      * run the efi shell
      * figure out which settings are applicable
      * save the appropriate crazy long string to vfat or something

And then I'd boot rEFIt and try to enter that magic "volume=0" string.
I suppose if this was a sane idea, it would also work just as well by
booting in efi mode and using the efivars kernel driver to edit the
value.

If anyone goes down this road, please pass along your results. :)
