Well, the 59 emails exchanged with Terratec users finally paid off, at least for the version of the product that uses the zl10353. With the help of Simon Kenyon, who was nice enough to let me SSH into his environment for a few hours, I was able to identify the problem, which ended up being a misconfiguration of the i2c gate for this board. To make things more confusing, setting the i2c gate parameters on the zl10353 when there is no tuner behind the gate actually wedges the i2c bus. As a result, the xc3028 initialization and first tuning attempt would go through, but after the first call to close...

The EVGA work is wrapping up. Both the ATSC and analog parts are working, and a PULL request was issued this morning:
http://www.kernellabs.com/hg/~dheitmueller/em28xx-indtube2
It seems that there is some sort of general problem with em28xx audio and Fedora 11 not specific to the EVGA inDtube. The user tried out the HVR-950 and saw the same problems.
On a separate note, the 2.6.31 merge window opened up, and in the end it looks like the KernelLabs developers contributed 44 patches for this dev cycle (not including patches submitted before we started using the kernellabs.com email domain...

I have been continuing to remotely debug Linux support for the EVGA inDtube. I actually heard back from an engineer at EVGA who was nice enough to take a look at the schematic and provide me with the GPIO map for the device. As a result, both analog and ATSC are working, but there is a problem with the audio.
Given the errors I am seeing in pulseaudio, I have to wonder whether it is some generic compatibility problem with the em28xx-alsa module and Fedora 11, as opposed to something specific to the inDtube. I do all my development on Ubuntu, but it's tempting to see if I can whip up a Fedora...
