Late-2011 R8911 value

Original poster

Long time reader, first time poster. I've been diving down the rabbit hole of ways to make my old Late 2011 Macbook Pro useful. I had it running on Ubuntu 20.04 before the dGPU did what the dGPU's do on these machines, and I got something else. It went into storage for a while until I pulled it out a month or so ago to try to get something (anything) running on it. At first I tried the naive apple advice of using recovery mode to reinstall MacOS Lion, which worked! And then I tried upgrading to High Sierra because I got greedy, and it broke again, wouldn't even boot. Since then, I've tried internet recovery for Lion (certificates expired, changing date didn't fix anything), internet recovery for High Sierra (machine won't stay awake long enough to finish the download), Ubuntu 22.05 LTS and 20.04 LTS (could boot off USB, tried changing grub options before installing but would never boot from HDD once installed), and Arch Linux (never got far). I was left with a machine that had no operating system to speak of and wouldn't take to any of the solutions I could find, so I got desperate and removed (then promptly lost) R8911, as I read this could help. Unfortunately, I definitely missed some of the other steps required to make that mean anything, so the startup chime sounds but there's no picture or apparent functionality, even after resetting PRAM/NVRAM. I tried bridging the resistor pins to see if I could get anything out of it, which obviously didn't work. I know this was dumb, but I'm really not ready to give up on this beast of burden, nor really spend too much money.
I couldn't find it online, so I wanted to ask here: does anyone know/can check the value of that resistor so I could potentially replace it? Or is there another path forward with further hardware/software mods? I don't have much to lose at this point, so I'm really open to anything.
