If it's like the iPhone 4 orientation locking, you click the home button 2x, swipe to the left, and then click the lock icon. The problem with iPhone 4 though, is that it only lets you lock portrait, and not landscape. This would tick me off if they only allow locking in one direction on the iPad.
But... surely they wouldn't, as most iPad apps to even be approved by the App Store have to rotate neatly in all directions. I'll repost my findings tonight, planning on putting 4.2 beta on my iPad to do some testing.
My guess is that it is a bug because they pushed it out for iPhone and iPod as well. On those devices it is a mute switch so I'm hoping it was just an oversight.
I hope that we have a choice with this, though I doubt it with Apple. Mute button seems pointless to me on iPad.
I wish Apple would give us the choice through a setting instead of forcing everyone to one way. But knowing Apple they will not do so.

If I want to mute, I just push the volume control down. If I am in a game, I don't want to have to close the game out and reopen in order to lock the orientation.
