As you noticed, StaticMesh does not load any textures. Internally the
mesh object uses basic D3DX-functions and interfaces which don't
support it. The more complex interfaces (ID3DXFile etc.) require much
more processing which is not usually needed. Actually, it is almost
easier to write a simple .x-parser in Python than to create fully
supported C++-loader with those interfaces. They are flexible, but
also quite complex.
It is quite common to use .x-files to only store geometry (etc.) data
and use some other file format to store other information. For example
a simple text file could specify information about an object, like
it's physical abilities textures and approriate .x-files (if it is a
composite shape or something). When you need to load an object you
just process this file and load all needed resources.
