Its an ACPI system, so you won't see all of the fun DTisms of a MSM chip.

The platform was fully functional upstream, and had an Ubuntu 
certification.  I run Ubuntu on the two that I have in my office.  I 
haven't strictly checked out mainline in a while, but I could.  I still 
have access to the documentation.

There is a small, but active set of users including myself.  From what 
I've seen, they've been happy with things.
