The current Linux implementation limits IP27 to cards with 64-bit
addressing capability.

What kernel version are you trying?

That actually also seems to be more of a limitation of how the IP27 code
is setting up RRBs for PCI devices, so any driver is expected to deliver
a somewhat modest (understatement!) performance. Fixing fortunately isn't
too hard ...
