I simply described how one ABI (ALSA <-> kernel in this case) can be stabilized, while new non-ALSA related features (and potentially unstable ABI) can still be had.
If computer has enough resources, practically every ABI can be stabilized (if desired) this way - as long as the ABI is PCI slot related.
That is, I can, for example, stabilize ALSA-kernel interface choosing (ALSA 1.0.11 + kernel 2.6.17) and I can stabilize TV card interface using (whatever v4l + kernel 2.6.18), etc,
