You pretty much need ubox, it looks like the kmod package is a bit sloppy in wanting to replace its contents...

I've only been able to have it work in NMEA mode at 4800 baud. Use gpsd with the -b option. If the BU-353S4 has been set to binary mode you may need to leave it unplugged for a few hours until its memory backup capacitor discharges and it resets to defaults.
