well, the raspberry just can't receive RF from userspace reliably. It drops a lot of packages. So maybe with a kernel module it's possible, however this way offloads the RF receiver completely. The arduino does a few other useful tasks as well, and can even decode IR for example eliminating the complicated programming procedure of LIRC. The arduino also can provide an additional serial port for nmea data.
