Hi Charlie,
To set a model's transformation to the identity:
identity = chimera.Xform()
  model.openState.xform = identity
The key thing to realize is that in a statement like:

	x = model.openState.xform

x is now a _copy_ of the transformation matrix -- making changes to  
this copy doesn't affect the actual transformation matrix.  To make  
the changes take effect you need to:

	<make changes to x>
	model.openState.xform = x
