And, I unchecked everything but what I need to run this card (I think,

Maybe somebody can take the time to tell me what I do need to run a
pcHDTV-3000 in both ntsc and atsc modes using this newer code?
I was under the impression I needed the cx88 stuffs, ORV51132 (for
atsc) and nxt2002(for ntsc), but now we have lots of other dependencies
out the wazoo. Please clarify.

These other dependencies have always been there, except that nxt200x and lgdt330x are relatively new frontends.

The difference is that a new Kconfig / Makefile feature is allowing us to only select the specific frontend needed by your hardware... Previously, all frontend support was forced to be built-in.

You and Adrian have clearly demonstrated that this frontend selection capability isn't working properly. I think I will send Linus a patch to restore previous functionality, forcing all frontends to be built... Then I will resubmit a patch to Andrew that will re-enable this frontend selection support, and I'll ask him to hold it in -mm until we can work out the bugs.

Actually, I think that I might have fixed it... Please test the attached patch.

The problem is that you are selecting cx88-dvb to be built-in to the kernel (not as a module) , but the frontends are being built as modules only.
