Tricking program into seeing actual gfx driver not WINE's

[Seth Shelnutt]

What options do I need to change in order to compile WINE with support for
the more GPU specific information?

Also when changing the following lines of code in order to change the output
of IWineD3DImpl_GetAdapterIdentifier to for now identify it as a 8800 GT
with 173 drivers, would the second lines of code be correct? I just want to
make sure "driver" actually means "driver" Which would be "nvidia 173.14"
and description simply the card correct?

        Adapters[0].driver = "Display";
        Adapters[0].description = "Direct3D HAL";



        Adapters[0].driver = "Nvidia 173.14";
        Adapters[0].description = "Nvidia 8800 GT";


Also if this is the case would it not be easy to simply grab the driver
version from the xserver, or atleast the xserver would give you the card and
brand, Nvidia 8800GT but I am not sure how to get specific driver
information. I'm looking for a command but glxinfo is only opengl info, and
I've yet to find anything else.
