    kernel: add IEEE-1284 parallel port support
    
    The kmod-lp package included both lp.ko and ppdev.ko, but ECP device
    drivers may or may not require lp NOT to be loaded, needing only ppdev.
    Additionally, There were no packages for any parport interface modules,
    such as uss720 or parport_pc, provided here. It has not been otherwise
    possible to use PC-style parport hardware for kmod-lp.
