The PVR features will work with any card, it does not have to be paired, even a blue one.
Don't dump the memory, just use the non-serialised version and edit the S/N so that it matches the box if the card is paired, you can find out if it is paired before starting the process. If the card is not paired, you can read the box key using oscam on a linux receiver. Bear in mind, that no entitlemnts on the card sometimes shows as you have "entered the wrong card for this receiver" even though the card is paired.
On that thread, people have cloned the main receiver and patched the pace so that it reads the official card in a "holiday receiver", don't know how it affects the new HD pairing system though.
My brother is not using his one, I'll see if he wants to sell.
