I post something via gmane this morning, but it seems it was lost :

Did you check if there aren't multiple configuration for rtc (one with 
irq, and
one without it) ?

What's the ouput of 
$ for i in /sys/bus/pnp/devices/*; do if [ "$(cat $i/id)" = PNP0b00 ]; 
then cat
$i/resources; echo options; cat $i/options; fi; done
