I think it depends a lot on the texture although one possible trick to get a passable bump map is to run the texture through a high pass filter in photoshop. Gives you a nice 50% grey base with light and dark areas (Got that tip from 3D world magazine)
It's a bit of a black art really - apparently the best bump maps are hand painted :)
