I wonder how pervasive the 0x6fff (or 0x7000) test is in the player software.. is it only in one place, near to the actual disk access code... ?

It's only in one place, but sadly it is in the player; it doesn't just rely on the kernel's you've-read-off-the-end-of-the-partition error (which would have made your job very easy).
