Wow,
I just found another great mini golf game.
This one is fully 3D. It's called (unfortunately) Harry Putter's Crazy Golf. Bad name, but the screen shots look fantastic.

The min. requrements are a 400MHz XScale - so my x3i will barely run it - but I'll let you know of the results when I try it some time.
