On cards with an OPL4, it would use the entire range, where that last
eight bytes are the OPL3-compatible registers.
AFAIK the opti93x chips have an integrated OPL3 and cannot be used
with an OPL4.

My card doesn't have PnP, but I guess the OPL4 detection wouldn't work
on 92x either for the same reason.
