Are you talking about ABI of kernel modules?
Of course different $MACHINEs have different ABI in kernel,
but i386 and xen have the same $MACHINE, don't they?
Probably you should mention kernel modules for sun3 vs sun3x,
but I don't think it's a good idea to bother to split single
modules into multiple variants.
On the other hand, most userland binaries (even with libkvm)
can be shared among mac68k, sun3, and sun3x.
(though some binaries like disklabel(8) can't be shared)
