Yes. It only supports the CS5520. If it detects the CS5530 it states:

PCI: Using IRQ router NatSemi [1078/0100] at 0000:00:12.0

But does not touch any register. My upstream patch was rejected, as it breaks 
all the lousy CS5520 targets with broken IRQ routing tables.

But I can live with the patch on my target. Nevertheless I would be happy when 
LB does this job itself.
