Why would you want to? ia64 already has its own perfectly good Linux port.

That's `11i v1.6'. Quoting from
PA-RISC binary compatibility
HP-UX 11i version 1.6 includes the Aries dynamic code translation
technology as an integrated component. Aries is built on the close
relationship between the PA-RISC and Intel Itanium instruction sets
and provides binary compatibility for PA-RISC binaries on the Itanium
processor family. Aries can be used where performance is not critical
or where it is not possible to create a native Itanium processor

Not particularly close. If you look at the assembly language level,
there's a lot of similarities, but there's a lot of differences too.
