Should the number in /proc/interrupts for empeg_rdsirq be this high on a machine with no tuner (and without a Hijack fake tuner)?

0: 4 empeg_state
1: 0 empeg_usbirq
2: 0 empeg_cs4231
3: 22678580 empeg_rdsirq
4: 3358446 empeg_input
6: 36298 ide0
7: 27438 SMC9194
17: 140 serial
20: 729948 audio-empeg
26: 1906854 timer
FIQ: cs4231dma

It's rising more rapidly than any of the other lines - over 1000 per second. It makes no difference whether the player is paused or running.

Looking at /proc/empeg_rds gives just the single line

Log:

which doesn't seem exceptionally helpful.

Is this normal? Can anyone explain it all?
