MacBook Pro Screen Flickering

I’ve had my MacBook Pro for almost a year now and I haven’t had a single problem with it, that is until recently. I’m guessing that the install of Snow Leopard has triggered a bug somewhere in the system that causes the screen to flicker. The only time I’ve noticed the flickering screen is when I have an external monitor connected to it.
For those wondering, this is what the flickering looks like.
Some people have been saying that you need to zap the PRAM but others dispute as not doing anything. I’ve found something that seems to work. This is obviously a bug somewhere and I hope that an update to Snow Leopard fixes this sooner rather than later (I’ve heard it’s supposed to be the next update).
Go into the Energy Saver Preference Pane and change the Graphics option from “Better battery life” to “Higher Performance”. After making this change, the screen no longer flickers. Obviously this is going to chew through your battery like there is no tomorrow, but it can be toggled back and forth (NOTE: To toggle this setting you need to logout of your user account and log back in).
