Hi Nicolas,

Nice to get more feedback, especially from people we know and trust ;-)

I didn't know about this nv/nvidia config rewrite issue. I wonder if it 
could be related to a postun/post script mix-up when doing an update ? At 
least, that's how I interpreted the "at the same time".

As Phil indicated, we know about an incompatibility between the kernel 
module and the Xorg driver, if the kernel module is not unloaded/reloaded, 
restarting Xorg (with the new driver) will fail. I think it failed with a 
segmentation fault, I already regret not having reported it ! :-(

That is why the advise for rebooting, unloading the module is not possible 
when in X. And the whole init 3; rmmod ...; init 5 dance is probably 
wasted on most people.

Even though I personally hate to recommend rebooting...
