It is compatible, kind of. The sensor reading you are getting are from
the new asus_atk0110 acpi module. Unfortunately this module doesn't
have pwm support yet. There is a problem where the old it87 sensor
module that you would have used for pwm in the past has been
intentionally disabled in the new kernel (2.6.31 I think) because it
was using the same resource that was reserved for ACPI. I don't
understand really but that is what I found with googling around. There
is a command you can add to grub that will relax this kernel
restriction and let the it87 module load anyway. That is what I did
and it works fine for me. Some have said this could cause problems and
other say it doesn't matter as long as it works for you. I think I
also had to install lm-sensors 3.1.1. It wasn't in the Ubuntu repos so
I downloaded the deb file for debian testing at packages.debian.org.
You could just install it from source as well.
Another option is to roll back and use an older kernel. I can't find
what I was looking at in the Ubuntu forums, but here is the bug report
that identifies the issue and gives some solutions.
