So an interesting thought here is that GRUB also supports the =
setpci command,
and runs early enough for it to matter. This would be the functional equiva=
lent
of an early pci quirk. If someone having the issue could try adding

setpci -s 01:00.0 0x488.l=3D0x2000000:0x2000000

to be run by grub, and reporting back whether that helped or not, with `lsp=
ci
-nn -d 10de:` output, that'd be interesting to see. [Not everyone can use
01:00.0 -- double-check where your GPU is at. But that'll be right for most
people.]
