Did you tell the linker about the DLL? See section 2.3.4 of 
"Distributing Python Modules" on how to specify a library in a setup.py 
file.

An aside. Python is built with VS2003 and so uses msvcr71.dll as its C 
standard library.  I don't know how it will behave with an extension 
module linked to msvcr80.dll . In fact, I am surprised Distutils 
recognizes VS2005. But you should be safe unless your module does 
something extreme like call free() on memory allocated by Python's 
PyMem_Malloc() or fread() on a (FILE *) retrieved from a Python file 
instance.
