That's really useful sharing of your own way of thought to trace down the issues. Please share more of your experience here!
It is definitely helpful and intuitive to follow your steps on tracking them, where I am really novice in reading and tracing the source code and the linking between them.
The uboot(kernel 3.8) use the dtb in boot/dtbs base on the board name defined as this $this->bbcode_second_pass_code('', 'board_name=A335BNLT')
$this->bbcode_second_pass_code('', ' findfdt=if test $board_name = A335BONE; then setenv fdtfile am335x-bone.dtb; setenv fdtbase am335x-bone; fi; if test $board_name = A335BNLT; then setenv fdtfile am335x-boneblack.dtb; setenv fdtbase am335x-boneblack; fi; if test $board_name = A33515BB; then setenv fdtfile am335x-evm.dtb; fi; if test $board_name = A335X_SK; then setenv fdtfile am335x-evmsk.dtb; fi; if test $fdtfile = undefined; then echo WARNING: Could not determine device tree to use; fi;')
So, I think it is using am335x-boneblack.dtb which I emphasise it in the post.

I got this from /boot/dtbs in dtb file format and decompile it back to dts so that I can check the content of this file.
Then delete everything related to hdmi/hdmin, doesn't work.
I can see a lot of hints from you to further explore how the whole thing relate to each other and the change/progress over the kernel version.
