I like that idea about taking the bulb out! I think I'll give it a shot!
That light is REALLY anoying, and it is NEVER right (I run 31" instead of 29", so it's worse than in the stock configuration, which is already bad!). By the way, it tells you to shift based ONLY on RPM's, which do not mean anyting. If you hit the gas and hold the RPM's on neutral at 3K, the light will come on.
