Correct, Ultrix only ever ran on PDP-11 (not relevant to this discussion :-), VAX, and MIPS-based DEC equipment. We ostensibly support it for any little-endian MIPS platform and VAX, but I don't know how much real-world testing it's ever had on VAX. The Ultrix binaries you tend to find out in the wild are for MIPS, because every DECstation / DECsystem came with it.
Fundamentally, you need to have access to the correct architectures to test the compat modules, and you furthermore have to have access to the foreign binaries (and possibly also the foreign system run-time environments, if shared libraries are used).
