    # workaround nforce stuff.

    # modules.pm uses /lib/modules/VERSION/modules*map to know which
    # sound drivers to use : this'll cause i810_audio to override
    # nvaudio since it exports the nvforce audio pci ids
    #
    # the right solution is to :
    #
    # - remove the nforce ids from i810_audio until the oss driver got
    #   fixes implemented in alsa driver for nforce (snd-intel8x0.o)
    #
    # - ask nvidia to declare which pci ids they use and export them
    #   for depmod :
    #   MODULE_DEVICE_TABLE (pci, <name_of_the struct pci_device_id variable>);

    #- try to workaround nforce stuff.
