This doesn't work either.  No error --- it just ignores the setting.

DSP_BUFFSIZE is not among the options that are setable in the kernel
config file and any attempt to set it gives an error when config is
run.  I'm guessing that the only way to change this is by hacking the
header files in the kernel source.
