Fisheye lens: how to make a circular pano.

I have just bought a 8mm fisheye lens and seen images of round pano shots and wondered how this is done. If I shoot several images using the fisheye, will photoshop create a circular pano as opposed to a linear one from a normal wide angle lens?

Edit:
Just found this so will give it a try.

Edit 2: tried it and it seems to have worked using PS CS6. I used 6 normal linear wide angle images in portrait mode as a trial. Don't know how my fisheye will perform with this but will post back.
