I've been using an app called AntiLock (there's both a free and paid version). With this app, you have the options of No Lock mode and Skip Lock mode. No Lock turns off all locks so when you turn your screen on, it goes right to your home screen without having to do any unlock (No Lock app also does this). Skip Lock mode skips the stock swipe screen unlock and goes directly to your pattern unlock screen so you don't have to do both the swipe unlock and the pattern unlock. It's not perfect though. When you turn on your screen, it actually flashes the swipe unlock screen momentarily before going to the pattern unlock screen. And if you happen to hit the wrong pattern on the screen, it reverts back to the swipe unlock then pattern unlock. Closest I've been able to get to just the pattern unlock screen only, something which the phone was capable of doing before Froyo came along.
