bug#59361: linux-libre 6 breaks OpenGL on nouveau driver for nvidia 8800 GTS 640 Mo card

[Tobias Alexandra Platen]

That is interesting. Does anybody know which old GPUs will
work with linux-libre. On my Talos II, I noticed that even
old nvidia GPUs do not work, the POWER9 will shutdown the
link to GPU. I guess only AMD and Intel CPUs will work,
and maybe also the RK3399 which I was unable to test.
