It's never easy... :)

pre-cut the holes in the wood...

What I have done before is cut a piece of wood the same size as the control panel. I then cut out the inside of the control panel so there was only an inch boarder around the outside. Then take the wood and route a one inch boarder in the wood the same thickness as the metal. This allows the wood and metal to sit flush.

Oh - it's nowhere near this bad.  It's, quite literally, 6 holes.  Two regular button size and 4 small ones.  It's just making the new holes that's an issue. 

Leapinlew: That defeats the purpose of the top piece of wood giving stability to the drill bit and would be equivalent to just a piece of wood underneath.

leapinlew:
wouldn't the holes give your drill bit stability?

mgb:
If you're using a hole saw and a drill press, anything firm under the panel like wood should give you stability as long as its clamped well. personally I would not use a step bit as I find them to not be very stable.

Maybe not the cleanest method, but couldn't you just mark it with a pen and use a dremel with a grinding bit to enlarge the hole?
