The engine setup would trigger a bogus line write before the proper
addresses are setup, thus causing the card to try to bus master over
the system bus to some stale location (usually 0 but could depend on
whatever was used before X). Remove that useless init bit, and always
setup some good enough engine source & destination pointers in case we
have some other spurrious engine activity going on.
