    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.

    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 don't question the need for this patch in mainline; however, it does
    not seem to be suitable for -stable.

    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).
