Hmm?  That means the driver didn't load.

Hmmm... I wonder, maybe the driver is failing to load entirely if it can't
bring the ALSA interface up?  I will check that.

What does lsmod says?  Is it loaded?

Anyway, please run the driver with the "debug=0x0040" parameter, maybe it
will tell us why it is not working.
