More good news... 
I've finally had the time to hook up a logic analyser to the AS1130 and it seems that I have a problem when using the wire library to read the registers...I haven't yet figured out what it is...but over reading all the registers around the Interrupt Status Register actually gets to read it AND clear the interrupt bit....Yeeeeeeaaawwwww!
This is the final problem with this chip.... XD
Will keep you updated.
