Yes, the tools will refuse to patch a firmware version not on their whitelist. This is so that if Sandisk releases a new firmware that can't be safely patched, only a developer bricks their player rather then everyone who tries to update. This is unlikely, but we wanted to be safe since it would suck to brick everyone's player.
If you want to test you can remove the check in the code and compile your own mkamsboot that doesn't check, or just wait for someone to update the white list. We probably used to be faster about this since we needed the OF for USB. Now that USB works in rockbox, I don't think people are paying as close attention to the OF anymore.
