You are not alone PEPERRY, I just tried to test out my Vista 64's hibernation with the MA3 beta, and there is no sign of it. The option is completely gone.
I do know it was there a few weeks ago, as I was testing hibernation, just to see how long 4 GB would take to go in and come out of hiber.
But now the options are gone from the screen saver utility power settings, as well as the shutdown menu. I did some research and discovered something new, to me anyway.
There is now a HYBRID SLEEP mode. You can find out some info here...

I did what it said, and the hibernation mode did show up again. I set Vista to go to hibernation, and left the house. When I returned the PC was still running, but Vista did shut down the monitor, but it wasn't hibernating like it should have been. Oh, by the way, this is with no screen saver selected.
When I went to double check my settings, all hibernation references were gone.
This makes me think Microsoft broke something in one of its Patch Tuesday updates.
I really don't think that MA3 could have done this.
