Emboss maps are usually generated using convolution filters.
Try a search for emboss + convolution on the net and you'll surely find what you're searching for.

I guess that you want to do emboss bumpmapping? then the map you need is just a grayscaled heightmap.. ( and if your card hasn't all the extention needed, eg. texture env SUBTRACT, you need an inverted version of the same map)

If you want to create them yourself, you have to learn about convolution filters as someone else said (it's only way I've heard about).

edit: I believe ARB_IMAGING has support for this, so you can find what's it all about in spec (maybe http://www.opengl.org/discussion_boards/ubb/smile.gif)
