Peter Wemm 3e0f102e57 With this evil hack the DS1 driver works on our Intel desktop
motherboards that use YMF740's.  It has a strange subvendor and subdevice
ID and requires a disturbingly long delay after the ac97 codec init.
Cameron hasn't had this driver tested on another 740 yet, so we don't know
if this is a quirk of all 740's, or if its just something about the codec
that Intel used.
