I'm running an older "NVIDIA Corporation G70 [GeForce 7800 GT] (rev a1)"
card in a newer BIOSTAR B550GTA MB. Kernel 5.10-rcx does not work. I get
no virtual consoles or X screen.
My dmesg seems to show the cause:

drm/nouveau: move io_reserve_lru handling into the driver v5
While working on TTM cleanups I've found that the io_reserve_lru
used by
Nouveau is actually not working at all.
In general we should remove driver specific handling from the memory
management, so this patch moves the io_reserve_lru handling into
Nouveau
instead.
v2: don't call ttm_bo_unmap_virtual in nouveau_ttm_io_mem_reserve
v3: rebased and use both base and offset in the check
v4: fix small typos and test the patch
v5: rebased and keep the mem.bus init in TTM.
