[pvrusb2] AVerMedia HC80 AVerTV Hybrid ExpressCard/54 support?

I'm using a 64-bit 2.6.33.2 stable vanilla kernel, all the capture/frontend/tuner modules are enabled, and also things I thought might help (ie. CONFIG_USB_C67X00_HCD=Y, I can't imagine it needs host controller mode, I'm just "preparing".) I've pulled v4l-dvb from their Hg repository, and am working with pvrusb2-mci-20100221.tar.bz2. As suggested, I added new device elements to the pvr2_device_table and pvr2_device_desc structures. I cloned the simplest entry and modified that.

I'm wading much deeper than my skill level, but I am trying to comprehend it. With regards to the analog tuner, the Xceive 2038 has both it's own module & firmware in v4l__experimental, and in the kernel inclusion of ivtv's tuner.h as tuner #71. Also since I don't know any better, I've made new entries for ROUTING_SCHEME, DIGITAL_SCHEME, LED_SCHEME, and IR_SCHEME for the HC80 in prbusb2-devattr.h...

It compiles and installs and I get:

However, it at least does try and talk thru USB. "chip found @ 0x86" whether or not it's correct sounds like it was able to query something. And loading the module turns on the card's in-use LED, too. Would you consider that an indicator that the FX2 gets bootstrapped from that EEPROM? Also, if I modprobe wm8739 & tuner_xc2028 from v4l-dvb, they load, but do nothing. (and defining them as .module_id list items in pvrusb2 generates undef'd compile errors, go figure.)

As always, thanks so much for reading, and if there's any way you can help me along I'd greatly appreciate it.
