mine is SV21 0437. Guess you have 0438 and both should work as tuner=63.

Good, that is most important.

On current kernels the tuner by default is only enabled for DVB-T.
There are some special bits in tuner core code to enable it for analog
mode, which currently don't come through in the init sequences on first
load.
You will notice in "dmesg" that the analog IF demodulator tda9887 is
missing. You must reload the driver once and it will be there.
You might set options saa7134 alsa=0 in /etc/modprobe.d/saa7134.conf,
else on recent distros the audio daemons might hold use count on
saa7134-alsa and you can't "modprobe -vr saa7134-dvb", which also
unloads saa7134.
On the wiki should be some instructions for saa7134-alsa usage.

On radio autoscan does not work, since the tuner does not provide a
stereo detection bit, but sound is good stereo. Radio sound is better
with audio cable in the red connector.
Cheers,
Hermann
