#if 0
        saa7146_setgpio (saa, 3, SAA7146_GPIO_INPUT);
        cam = saa7146_read (saa, PSR) & MASK_06;
        saa7146_setgpio (saa, 3, SAA7146_GPIO_OUTLO);
#endif
        cam = 1;

With this change in ciintf_poll_slot_status to prevent spurious cam resets I 
have it decoding on a Conax 4.00e, 01, 0B00, 04B1. Any ideas on how to 
prevent those without this hack?

I also got the oops below while testing.

Nice work, both of you,
Kenneth
