2.6.32.something, can check exact version later if you want. alsa
userspace bits were upgraded at the same time (can also check from which
version later if necessary).

No, I mean that I've never used a model= parameter before, and in trying
to debug this new problem I tried model=intel which did not fix it but
model=no-jd does. So model=intel might have worked before.

On a related note, why is model=intel even there (and why is the end-user
expected to set it)? The docs says it's for DG45FC and DG45ID
motherboards, but shouldn't those motherboards be possible to autodetect
in the driver via DMI info?
