This worked for me!

Did it last night, and very happy to have the gestures back. It is hard to do without them once you are used to them.
It is claimed that this method does not actually result in jailbreak!
My iPad seems all normal after doing it (gestures now present of course), but I would be interested to hear others thoughts on this. . . . I know absolutely nothing about jail breaking.

Sorry OP, my post didn't really answer your question.
No, as standard, iPad gestures are not on the iPad 1 under iOS 5.
