On the LX2160A, there are lots (about 160) of IOMMU messages produced

I'm not strongly against this. But to me this message seems to be a good
indicator that a device was probed successfully by the iommu subsystem.
Keeping it in the default kernel message always helps to the kernel
debugging.
I would tend to agree.
