I don't recall anyone posting problems here with the open "nv" driver, period.
But that's not the point. The point that if someone did post a similar problem, then most people, myself or anyone else for that matter, could at least look at it, and do some poking to eliminate the most common problems. At the very least one could locate where any error messages are coming from, in the source code, which would narrow down, somewhat, the problem's domain. If the "nv" driver was crashing and taking down all of X.org, as a result, a backtrace can also be obtained, against pointing the finger in the general direction of the culprit.
None of the above is possible with the non-free binary blob. What kind of diagnostics can you do with it? Bupkis, that's what. Oh, there may be some rudimentary peeking and prodding one might be able to do, perhaps. But not to any extent the same level of debugging one can do with free drivers.
Last year, Mesa began crashing and taking down all of X, on an old Voodoo card that I have in one box. Yes, an old Voodoo card still had more than adequate accelerated OpenGL driver support -- more than enough to run MythTV on it. After taking down the backtrace, and dumping some additional debug info into the right Bugzilla, a few months later someone found the bug and fixed it.
Imagine that. Now what would be the chances of taking an old Nvidia card, for which Nvidia has discontinued all official support in their binary drivers -- because they want you, of course, to buy their latest heat dissipator -- and have anyone do /anything/ about this kind of a problem? I give you three guesses, and the first two don't count.
And /that/ is precisely the point. The original poster, I'm afraid, is royally boned. If he can't find the right toggles and prods to twiddle in his BIOS configuration, or some obscure X setting, he's boned.
