Or maybe you're not listening to enough Dream Theater.
Seriously though, what I do to come up with more interesting drum parts is I start with something simple, like a kick, snare, kick, snare... completely generic, and I'll start adding things, and moving things around, more or less randomly, give it a listen, then as I'm listening, I'll generally figure out what I do and don't like, and tweak from there.
No real set in stone method, sure, but experimenting is really the easiest way to come up with just about anything when it comes to music. If you don't know what you're going for, just start hitting things randomly, and sooner or later, you'll stumble upon a sequence of notes/hits that just sounds good.
