However, I identified the cause: maestro3 driver in 2.6.21 (even just > patch-maestro3-1) tries to load firmware file from user space.

Yes, some drivers (e.g. maestro3, ymfpci) require now external firmwares. Try to install them from the latest alsa-firmware package. I already added new Kconfigs to choose whether external or in-kernel firmware for 2.6.22. Anything else should be as it was. (The replacement with quirk list helper doesn't change the functionality.)
