Definitely possible.  Probably pretty easy.  It's very similar to the
amd serengeti_cheetah.  If you want to support it, you could start by
running superiotool to find out what superio you have.  If it is the
same as serengeti_cheetah there should be very little work required to
support it.

The wiki has useful information about superiotool and getting started.
