The report has some points not clear.

For one thing, if the problem occurs _only_ when the nvidia driver
loaded, the one made by nvidia, then you will have a very hard time
convincing anyone to even look at it. It is closed source! The kernel
puts a message saying "Tainted!", and developers will not touch it as if
it were leprous.

They have their reasons and I wont argue them, nor who is to blame, but
it is a sad situation for users, who certainly are not to be blamed.
This is like a city transport strike: they go against the management,
but it is the users who suffer it.

If they had given that answer I would be 100% happy with it. The
problem I have with the response I received is that it smelled very much
like a George Bush justification for closing the bug. You know the type,
an explanation that just can't be trusted.

You seem to be misunderstanding what "mce" is. A machine check exception is the hardware itself telling you that something has gone badly wrong. There is no interpretation involved in the software. The software just logs the message

If the mce says it is a hardware problem, you can count on its being a hardware problem


Well, your right as usual about my understanding. What I can't get my mind around is the fact that the mce(s) go away as long as the driver isn't loaded. I guess that's possible if the driver is calling hardware that doesn't get called otherwise. However, it just seems that if the mce(s) go away if the driver isn't loaded, the the driver or the systems response to the driver was the problem and not hardware.

I'm ripping out the nvidia card and sticking a substitute in to check.
