look in /boot for your current config and copy it to that folder. Honestly though Id be surprised to see it compile. 2.6.32 is quite old (almost 5 years), might be time to upgrade your kernel.
The DD CineS2 probably uses a driver that TBS doesn't have in their tree.
I'm not sure what tuner/demod are used in the 6991se. It shouldn't be to hard to add support for open source for it. Unfortunately it's a $185 card, kinda out of my budget to pick one up just to add support.
