I missed one line that was part of the module's output:

cannot find the slot for index 1 (range 0-1), error: -16

This comes before the other two.

Then I guess it was just a coincidence that the kernel with CONFIG_SND_DEBUG=y worked.

Take a look at /etc/modprobe.d/sound or whatever module config file containing the sound setup. You must have a line with

options snd-XXX index=1

and this conflicts with the actual hardware. Take a look at /proc/asound/cards. The secondary slot must be already occupied by other drivers that are auto-loaded beforehand.

Either add a proper index to that driver as well, or use slots option for snd module. The latter is a new option introduced on 2.6.25. See ALSA-Configuration.txt for details.
