Judging from the errors, I'd say it can't look up the handle it created.

Diving into the old dma implementation seems 

The handles for vram and gart could not be looked up, so guessing an invalid
entry was used.

Does setting dma_bits = 32 inside drivers/gpu/drm/nouveau/core/subdev/vm/nv44.c
help?

The old nouveau driver seemed to have commented out the part about 39-bits
support for cards < nv50.
