From a quick check on my OS-9/ARM machine, and from some a few chats with Allan Batteiger, it seems OS-9 for other processors doesn’t even have this. If you load an ARMv7 module on an ARMv6, fine, until it hits one of the instructions not available on v6.  I assume it’s the same for 68040 modules loaded on a 68000, and 586 loaded on a 386.

The main Module ID type is all they check.

 need to snag the DEFS file or open up the Tech Reference to understand the bits and what they do.
