Somewhat newb: Video problem. (A little more challenging?)

Okay, I'll try and be as concise as possible. This is my second hackintosh, first one was a breeze. (Thanks to RehabMan's guide) but this laptop has no guide and things being to get more tricky as I dive in.

Here's the PC: Toshiba Tecra R950 - PT530C (0CU02V) running Sierra 10.12.6 (Clover 4318) The Wifi I needed to swap out, so I've got that working now. Audio works fine. The only thing is Video. I can inject ATI and it'll show the Radeon HD7650 series (Though technically it's the 7570 but same driver), but only 5mb of vram when the card supports 1024 natively.

That's pretty typical of a computer that has both Intel and ATI but this laptop has dedicated non-switchable ATI only video card. The hardware dump shows that it's the only video processor available.

I jumped into Linux and pulled the LSHW output but there's a LOT of it so I'm including the relevant parts (or what I believe to be relevant anyway)

I was able to get everything including the battery patch from RehabMan to get the thing like 80% working but the lack of video support is brutal.

Anyway, digression aside, here's what I think I've figured out.

The device is recognized as 0x68411002 which IS supported natively by Sierra (10.12.6), but there's a command as part of the boot which is to pull information from the VGA BIOS using the 0x0C000000 register. Apparently though, many ATI mobile cards don't give this information out when pulled from that address.

I've been trying to find the bios for the video card so I could inject the VBIOS (I've seen this work for other cards with the same problem online) however there IS no bios anywhere for this card or so it seems. I'm having a hard time finding utilities that would allow me to rip the BIOS and I don't know enough to extract the video card BIOS information from a generic BIOS file.

Does anyone have any suggestions of things I could try, or am I running down the wrong rabbit hole? I've tried manually selecting various name classifications, it goes with Pondweed by default which is close. Am I misunderstanding what's preventing this from working? Manually setting the configuration in Clover doesn't help; Even though I can say it has 1024mb of VRAM, it still defaults back to 5mb.

I only know enough about manual patching/hot patching to do things like turn off external GPU's and use IGPU (_DSM to XDSM stuff) but that's not really relevant here.

Does anyone have any idea of things I could try from here? I can post whatever information is needed from within the Mac itself as well if it'll help.
