amdtemp module does not find any sensors on 5.99.55

I've just updated my main server from 5.99.52 to 5.99.55 and it seems
that the amdtemp module no longer registers the CPU temp sensors. This
was working on 5.99.52.

If it matters, this is on a dual-Opteron-6172 (2 sockets, each with 12
cores).

Anything in dmesg?

Nothing in dmesg, nothing in /var/log/messages, and nothing on the
console.

And it is also not working on my Phenom-II (6-core) processors.

Seems it is probably related to recent change to modularize it. In
5.99.52, it was compiled into the kernel and working fine. But with
5.99.55 it has been modularized and not working.

So it does not even attach?

As an added datapoint, amdtemp still attaches and is functional if the
driver is built into the kernel, as is the case in the amd64/GENERIC
kernel. It seems to fail only when loaded after autoconfig is done.

I will try to look into it in the next few days...
