I am very happy to employ my time, system and very limited knowledge to help take this to the next level - so, standing by El Capitan Cheesestraws!
Well! Grab the New Tango 2.0 patch from this post:
Hanlon's razor applies here. In the absence of any evidence to the contrary, cock-up is more likely than conspiracy. Hanlon's razor is a wonderful principle, thanks for the lesson. The linked article's timeline explains why it didn't make its way into my 1970s Philosophy courses. Given Apple's...

which has the installer in it, and run it and see what happens!

You don't need to do the ResEdit mucking about or anything.
Several people upthread have said they needed to reset their PRAM afterwards or before to get it to work: I've never had to, but I may just be being lucky or careful in some way I'm not thinking about.
I want to emphasize my previous mention that I can’t even get a supposed plug and play usb card with the Opti FireLink chip to work which is particularly frustrating.
That
is weird. But if the Tango 2.0 appears as a pci-bridge, it's at least recognising the card is there. I'd try this before blaming your machine.
I’d also be really interested to know your take one the MagGarden guy I mentioned in my Reddit post who supposedly got this thing working stock without your patch - not that we have a way to get him online to comment further.
On this page?

If so, the card shown there is the earlier Tango 2.0 revision. You can tell because of the unpopulated IDE connectors at the top. The later Tango 2.0 does not have these, and is actually a totally different layout. Those have always worked well with the Sonnet-provided patch. I have one of those too, and it works fine with the original patch.
To clarify (or perhaps muddy further) a couple of confusing points about this whole mess that you raised in your reddit post:
- I don't know what the difference is between the different versions of the firmware "patcher" from Sonnet. As far as I know there's only one "patch" out there at all, I've seen it in the Sonnet installer and also in one provided by Orange Micro. I suspect this patch was actually written by someone at Apple and handed out to multiple hardware manufacturers, but this is only a suspicion. I wonder if it was just Sonnet improving the patch installer? My patch installer is ... rudimentary.
- It's not actually a patch in that it doesn't really change anything in the firmware at all; it's just a script that gets run on startup, more like something like AUTOEXEC.BAT for DOS. This should make it sound rather less scary, because there aren't even any semi-permanent changes. The script looks obtuse, but all it actually does is manually create the devices the computer ought to have found for itself, but didn't.
- There was never a second patch for the second revision of Tango 2.0s as far as I know. They printed compatibility for all those machines on the box—when they found out that they weren't compatible with all those machines, Sonnet literally patched the box art with white sticky labels over most of the names of the machines. Again, if the patch had originated with Apple or a third party who had declined to update it, that would make sense of this series of events.
Last, I want to get clarification whether I should or should not employ the helper tool to take my system to 9.2.2. It seems like in the thread this introduced new problems into the equation. Of note was how it apparently broke Ethernet card operability (?) which I definitely don’t want to do as that is an even greater goal of mine on this unit. I have an Ethernet pci card enroute that I hope to get working in here so I can once and for all put away this scsi ext drive.
Well, the more weird patches you have installed, the more problems you're going to have. I run 9.2.1 on mine, never bothered with the helper. Perhaps someone who has can chime in.
