python 2 coercion

Dear python list,
What happens (on the C level) if the python interpreter executes
a statement like
if <some strange extension type> == None:
....

Just a hint to the "entry point" would be great... What function/method
is called for the two operands?
I guess it is s.th. like PyObject_Compare or a type objects
tp_compare method, but am a bit lost.

Problem is I need to get an older number extension to work with python
2.3.4.
It worked with 1.5.2, and everything still seems to work except for ==
comparison.
I suspect that somewhere on the way some coercion is tried but does not
work,
but fail to see the steps that lead to this situation.

Thanks,
Holger
