The problem is that -stable patches should not introduce regression. And if this patch would be included in the next -stable release, people who upgrade to this release may get unexpected changes of sound cards indexes. This may be OK for a new 2.6.x release, but not for a new 2.6.16.y. > Indeed, on my system (an A8V Deluxe motherboard, with this > quirk active), my first soundcard (given index=0) is an offboard > Creative SB Live, and the onboard card I have assigned index=1. Yes, now I have exactly the same setup. But before this patch I did not have any index=N assignments in my configuration; after the patch I needed to add them to get my system working as before. > I for one need this quirk to get both soundcards at all (which > I need) -- no matter what indexing order.

I, for one (however much that is), don't need it either. Currently I get: VIA 82xx Modem: probe of 0000:00:11.6 failed with error -13 on every boot (and snd_via82xx_modem module in memory). Not a grave bug, but not a good thing either (and another reason for not adding this patch to 2.6.16.y).
