Yes, if we're behaving differently between different host
endiannesses then something is definitely wrong and my
suspicion would be that it's the test harness code.

No, that's very unlikely. I think if you are using address_space_read/write then you must use DEVICE_NATIVE_ENDIAN, but I cannot check as I'm on vacation now, about 6 time zones away from anything big-endian.
