You can disable or delete the Apple audio driver for the onboard sound. I believe it is AppleHDA.kext. The hardware will still be there of course, but it won't be used by OS X. Unfortunately most cheap audio adapters want to use that driver too, so you'll need a card that has its own manufacturer's driver.
