My laptop can't hibernate - it just doesn't resume. Is it a userspace issue or kernel space? How to debug it? Frankly, I don't care.
My another notebook with crappy Poulsbo video card fails to resume from suspend-to-RAM in about 10% of cases. Oh, and it uses a proprietary driver. You do accept kernel bugs for proprietary drivers, don't you?
This change is nuts. There are good use-cases for doing just nothing instead of inventing 'solutions' aimed to work around the bugs in certain hardware.

If you don't care, ignore it. If you care, file it with the hardware details, kernel version and let the developer ask for more information if necessary.

I've had experience with an attempt to post a bug for a tainted kernel. I don't want to repeat this experience.

Easy enough to see whether any proprietary drivers are resulting in the breakage by disabling them temporarily. If the problem is still there, report to LKML. If not, consult with the proprietary driver vendor.

No, it doesn't happen. However, there's no Compiz and OpenGL running and I'm fairly sure it's caused by Compiz.

Then file it against Compiz. I don't see the reason to resist doing that if you have already figured out the source.

Expecting software designers to cater for bugs that haven't even been reported is pretty unreasonable.
True, but then ikm never said he expects software designers to address these bugs.
I don't report bugs. The probably of the report resulting in a fix is too small to justify my time. I just accept my loss and look for the next best alternative.
I'm cognizant of the fact that if the bug affects only me, there's a vanishing chance that some developer working for free will be interested in fixing it, and if it affects a lot of people, someone else will have reported it or, better yet, some developer with the means to fix it will have experienced it himself.

At this stage, if you have a machine with an in-kernel graphics driver and it fails to suspend or resume then there aren't huge numbers of people reporting the bug. Really. Suspend/resume is part of the certification process for RHEL now and I get all the related bugs. There simply aren't that many, and in general it's something like hibernate failing because someone's swap partition vanished. I really would encourage you to report any suspend/resume issues to bugzilla.kernel.org and the massive probability is that it'll be tracked down quickly.

Even if there's an NVIDIA blob involved?

If you can repeat the bug with nouveau, then file it. If not, file with nvidia. I'm afraid that I work for a free software company, so we tend to make decisions based on the code that we actually ship.
