Think of the extra ROM as an Autoboot ROM and I beleive the solution
become aparent.  Commodore will have to allow the A690 access to the Audio
output of the Amiga (in order that mixed Amiga Audio/CD Audio be possible)
and will also provide a driver/filesystem that is capable of generating
input events (as the remote control generates these, and some stuff uses
the new RAWKEY code (PLAY/FF/REW/STOP).  I don't know how the gnelocking
stuff will work.  There is however a different problem with thge A690
running CDTV titles on an A500.  The CDTV has 1Meg of chip memory, and
as CDTV apps tend to be heavy on digitized sounds, it tends to be used.
Many programs may refuse to run on a 512k chip memory machine.
