When 2.6.15 was released, we had ALSA 1.0.11rc2.
I understand. Still, 2.6.15 has 1.0.10rc3 and current alsa "stable" does not work out of the box with it (at least for some of the cards and in my tests - hmmm, maybe this only happens when running with the -rt patches?).
There's one additional tiny patch needed in alsa 1.0.10 if you want snd-rtctimer to be detected by configure and subsequently built under 2.6.15+:
