A late change in the patch changed the implemented ID to one that
hasn't been used yet to avoid any ambiguity. Unfortunately the
chosen value of 0xFF matches the value of -1 which is used as an
invalid implementer so the test started failing.
This patch changes it to 0xFE which is the highest usable number.
