I never clear the interrupts so I should see it shouldn't I?

Thanks for the tip, the interrupts work just fine. I'm still not
getting anything from the CL-PS6700 controller so I'm inclined to think
that it is in fact fried. I'm almost positive that my code for enabling
everything in the chip is correct. I'm waiting for a reply from Cirrus
to find out what they think

Yep, already did that, the interrupts won't even happen unless I enable
them by writing ones to all three Interrupt reserved registers.
