Edit: Right, the one user I had test a couple of changes, first claimed this had fixed it…and then, now, later said it was back… And now another claim that it did nothing, so I’m removing the changeset as it’s pretty conclusive that it doesn’t change anything. Sorry for the noise.

Same here.

Because of this useless bug, DRM is NOT working…
Are NVIDIA developers on holiday?

That particular warning (the underflow one) shouldn’t, to my knowledge, have any effect of the DRM subsystem.
What’s the problem you’re facing, exactly? Missing HW acceleration; decoding; general crashes; or the like? If that the case, I would recommend opening a new topic for that.
You can, at least, test direct rendering by installing whatever package on your distribution got glxinfo, and running glxinfo|grep 'direct rendering'
Lastly, any “holiday” they might be having is probably just due that pesky “flu” that got everyone all riled up at the moment.
