Yes, if the nvidia/X driver fails in the wrong way, it can take out the
machine completely.    I have had it do it on at least one of my machines
several times.    And it changes depending on the version of the card, it
can change depending on the kernel and nvidia and X driver versions.
There is really no easy way to validate that the combination works completely,
and things can change with updates.

And I have noticed that using GL or xvmc increases the chances of software
issues (both appear to be less carefully tested, so more mistakes get
through).

If both frontends are identical hardware (and maybe just identical video cards) 
and they both have identical software the would both crash the same (if it were 
a software issue, if it were a hardware issue it would be unlikely for them to 
have the same failure.).
