<pre>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 equivalent
of an early pci quirk. If someone having the issue could try adding
setpci -s 01:00.0 0x488.l=0x2000000:0x2000000
to be run by grub, and reporting back whether that helped or not, with `lspci
-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.]</pre>
