I do not think the registry is the correct place to look. This value should 
return true if e.g. hardware accelerated T&L is available on the system, which 
is primarily a result of driver and hardware capabilities.
My current understanding is that a D3D caps struct would hold such 
information. The question now is which flag or combination of flags in it 
would cause the dxdiagn values to be 'true'?
