The module complains when it encounters an error, otherwise is very silent...
In this case it seems that it's not even trying to attach to the hwmon
interface.

I need a copy of the DSDT (/sys/firmware/acpi/tables/DSDT).

A copy of DSDT file is attached.

Ok, you were bitten by this bug:
http://lists.lm-sensors.org/pipermail/lm-sensors/2010-January/027633.html

Fix is already present in Linus' tree, you can find the patch here:

Thanks! That worked!

But it looks like the module doesn't support PWM outputs... I couldn't
get much information from Google, and reading the source seems like it
only supports temp/volt/fan sensors. Is this correct? Is it planned to
support adjusting the PWM outputs in the future?

Best regards,

Direct PWM adjustment: no, it's not possible with the ACPI driver.
Q-FAN: maybe, but so far I've been unable to decode the interface.
