At first glance there seems to be no feature to do it. What you might
try (I haven't), is that presuming that all output is generated through
calls to req.write(), is to substitute the "req" object with a wrapper
class that provides its own req.write() which is actually the write()
method on a StringIO object.

class Wrapper:

  def __init__(self,req,write):
    self.__req = req
    self.write = write

  def __getattr__(self,name):
    return getattr(self,__req,name)

s = StringIO.StringIO()

page = psp.PSP(Wrapper(req,s.write),  "template.psp")
page.run({"spam": 1, "eggs": 5})


If you were also stashing stuff in "req" from the PSP page, would also
need a __setattr__() method in the wrapper.
