I imagine they've hacked the DX9 drivers to use some of the hardware 
functionality that is only exposed under DX10 (and thus only in Vista).  I 
would highly doubt that they have managed to replicate the Vista graphics 
system on XP, so there is no way all applications designed for DX10 are 
going to work.  To do that they would have had to pretty much rewrite the 
whole Vista graphics system and parts of the OS GUI to run on XP, which 
seems a bit unlikely.
