Weird (I hadn't seen that you reported the 9235 working...), I have
IOMMU problems with a 9235...

What system are you running it on (when you say "power box", is it a
beefy x86 computer or literally a PowerPC)?
For me, AMD 990FX chipset, latest master linux.
My board works fine* on another non-IOMMU system.
