AMD's Damon Muzny was able to shed some light on the situation, and released the following statement to DailyTech:
There were a couple of "corner cases" (meaning very rare situations) where there needed to be a correction of how C'n'Q worked with some power suspend situations. Basically, if C'n'Q is already working on your machine, this won't change anything. No performance impact, period.
