   After getting some sleep and thinking about how IOMMUs work on parisc,
   I've convinced myself the CPU caches are virtually tagged and
   virtually indexed.

Some quick googling suggests that they are physically tagged.

For example, see section 1.1 of the following paper:

It's an interesting paper btw too :-)
