Those wild print out about add_size is used to double check if the
option size is passed correctly.

diff between 3.3 and 3.4:
in kernel 3.4, 1c.0 pref mem64 get allocated before 1c.1 pref mem64.
that should be caused by: We replaced local version resource list with
generic list.

But that should not be reason for why 3.3 does not work on Kamil's setup.

I would suspect that pci pm change fixes the problem.
