Ok, after battling pneumonia for two weeks, I'm finally tacking this issue again.
I pulled the driver's side airbag sensor, and it looked like this:
Here's the frame where it was bolted down:
The cleaned frame, along with the two grounds removed and cleaned:
Here's the passenger side sensor. Much cleaner than the driver's side.
The frame (could only get one hole photographed):
I coated all ground and frame areas with GM dielectric silicon grease prior to reinstallation. Powered everything back up, and...
... the light is still on.
The more I've read into the FSM, and the more I learn about the DERM, I'm inclined again to suspect the DERM here. It seems that if there's an energy reserve voltage low issue, and the DERM stores and manages this energy, the DERM is likely at fault. I'm guessing the DERM keeps the reserve current in capacitors, and if they're on the DERM, that's gotta be it. There is the possibility that the dual pole arming sensor is bad as well, but I"m leaning toward the DERM.
Any input is always appreciated. I can get both parts for around $50 each used, so it's not a bank breaker. I just hate throwing parts at something without a plan to get it working first. Wastes time and money.
By the way, that passenger side sensor was a bitch to get out. I managed to do it without taking out the heat/AC blower, but not by much.
No personal experience but have been told this company repairs DERM's, just another option in case you do not want to buy used, good luck.
Tried this today with both plugs, light is still on. I still think it's the DERM or the dual pole arming sensor.

Well, after pneumonia, overtime at work, and other life things, I finally got around to putting in the dual pole arming sensor. I put it in, started the car, and...
...no more airbag light!
The dual pole arming sensor was the problem. Now I get all flashes, light on during key twist, and no more light after the 2nd set of flashes.
While I had the dash pieces out, I also installed the resistor mod to kill off the SYS message about the absent dimmer on the aftermarket stereo. I even fixed the broken arm on the cup holder cover. Great to have all of the codes cleared.
Thank you to everyone that contributed to this post. Thanks again also to Hib and gmjunkie too!

where is dual pole arming sensor located at? does any one have a part number for it also? Thanks
