Interesting, I've always looked at the PA6T as a more powerful processor intended for Apple laptops (as the G5 was just too power hungry).
I haven't heard any reports that Apple was looking for a buyer for the PA6T, but as you pointed out they'd need an interested party.

If Apple has ceased production then the product will only be available till supplies run out. This is not a good situation for A-eon.

On paper, the design is impressive. I wonder what problems have kept it from being released to the beta testers?
