Hmm, I must have somehow missed this series when you orignally sent it.
Can I ask you to resend it, as I don't have it in my e-mail client archive
any longer?

While at it, I would also ask you to add my private e-mail address 
(this one) and linux-pm mailing list to Cc list.

Thanks in advance.

Best regards,
Tomasz
