… which would make the path depending on the linux-headers version.
Better, pbbuttonsd should do something like this:

  struct stat st;
  const char *path;
  int fd;

  if (stat("/sys/module/usbhid/parameters/pb_fnmode", &st) == 0) {
      path = "/sys/module/usbhid/parameters/pb_fnmode";
  } else {
      path = "/sys/module/hid/parameters/pb_fnmode";
  }

  fd = open(path, O_RDONLY);

Michael
