the possibility that this was done is very very believable i have researched the chips in the controller and in numerous other device and found that a lot of devices are easily programmable if someone knows the proper coding language for that device.
Psgroove is a simple repeating code that could be easily converted to other systems with a little coding knowledge.
i'm leaning toward this being a teensy in an old sixaxxis with a dpdt momentary switch that just allows the teensy access to the usb while the button is depressed. cause it seems to look like he's holding down the button while powering on the ps3 doing the power / eject then once the exploit is loaded, he releases the button, removes the usb cable then powers up the controller to show the exploit and controller works.
after rewatching the video, i notice he doesn't remove the usb cable, but during the power on sequence with the controller attached and while he's holding the back button, the controller receives no signal and lights up no lights on the controller. it's only after he releases the back button and hits the ps button to power up the controller do the controller power leds light up. this leads me to believe it's just a switch and a teensy board in the controller.

It might have something to do with the rapidfire mod he has on the controller, as in maybe he has been able to push code to a chip onboard but using the the 555 pic rapidfire mod that will send the pulse and work much in the same way as geohots sploit.
This is all speculation until he releases a tut on what to do.
