	SB Audigy chipsets are also treated differently for both cases. My Audigy 4 card for instance is detected with both drivers, but only the 10kx driver works with the card; similarly IIRC there are some things that work with the 10k1 driver that don't work the same with the 10kx.
	So while this would be nice to have, I'm not sure if it's an effective use of FreeBSD's time to invest in as these chipsets are effectively obsolete.
Thanks!
