Just a quick update, I was able to get the card working under linux using the dvb-utils. Basically, you have to use the card=17 option when loading the cx88xx driver to force the card to load as a Gold-Q card, which has the same chipsets on it.
Be aware, the original Gold 3 card does not support QAM, only ATSC.
So, for now you can use the card=17 option to get your original Gold 3 card to work, and native support of this card should make it into the 2.6.18 kernel.
I couldn't post the URL since I'm a new member, but you can follow the message thread posted above to see my post about the success and the reply from the developer.
