Well, read access to the status registers seems to make the mt352
unhappy.  It's not clear why this happens on that card.  According to
pinnacle the IRQ line of the mt352 is connected to GPIO pin #23 on the
saa7134.  So it should be possible to stop polling the status
registers and switch to a IRQ-driven handling.


#define printk(args...) fprintf(stderr, ## args)
