I don't know about the setup.py part of your question, but as for
choosing between 2 modules at runtime:

#file foo.py
#assuming 'foo' is the desired name of the module
from sys import platform
SUN = 'sunos5'
LINUX = 'linux2'
WIN = 'win32'

if platform == SUN:
    from x_1 import *
elif platform == LINUX:
    from x_2 import *
elif platform == WIN:
    from x_1 import *
else:
    raise RuntimeError, "Unknown/unsupported platform"


Cheers,
Chris
