> Think that they will use any of Intrinsity's gating technology?

It's well known that the Cortex-A8 core in Apple's A4 chip uses Fast14, and in the linked posting minator said:

"Before they were bought, there were rumours of Intrinsity working on a 2Ghz Cortex-A9."

From this I presume that also the Cortex-A9 core in Apple's A5 and A5X chips uses the technology. Thus I find it highly plausible that Fast14 technology has been applied to the custom core in Apple's A6 chip as well.
