Did you try to reduce it to a simpler structured example and see if it has 
to do with OO, or is it a 100% output buffering issue?

  I reduced it from the XML_Transformer_Driver_OutputBuffer class already
  to the code I posted.

  I'm not 100% sure but I think a "normal" function works as a callback
  for `ob_start()` -- so maybe it's a OO issue.

Procedural example works as expected. It seems that ob_start(array(object, 
method)) is the one causing problems.
