Getting DirectX emulation to work

[David D. Hagood]

Since I can no longer get OpenGL textures to work under Wine, I'd like 
to try to get the DirectX emulation working. However, when I configure 
an app to use DirectX, I get a "You have selected a mode your graphics 
card does not support" message.

Since the color depth and resolution are the same as OpenGL settings 
that work (save for the hosed textures), I would think this should work.

Are there some magic registry entries that need to be created?
