Well, that is what I was thinking also. But, there is this but: I post you and interview with a guy from Canonical about UNR:
What have you done with Intel to optimize the new platform for Atom?
Canonical has been working closely with Intel for more than a year on support for the Intel Atom processors. The optimizations mostly center around taking advantage of the power-saving extensions afforded by the Intel Atom processors, as well at some boot optimizations.
And this concerns only UNR. That was my doubt.

I'm glad to read that everything works good for you.
AFAIK, the standard ubuntu and the netbook remix version use the same kernel.
The netbook remix version is specific for netbooks in the sense that, as you probably already know, it does not use the standard gnome desktop, it provides a new desktop interface thinked to optimize the limited space available on small screens.
