I didn't work out the reasons, but the solution was simple -- just put the samplers back in. Since then, regular texturing paths appear to have lost their associated samplers which required a fuller investigation and fix in nouveau. Now that this is done, this code should no longer need a sampler state for fetching texels from a buffer texture.
