Nvidia-glx upgrade will "break" sytems on feisty upgrades

[Matthew Garrett]

Given that nvidia-legacy and nvidia aren't installable in parallel, I 
can't see any trivial mechanism for fixing this - the dependency system 
can't take hardware into account, and so there's no way to tell whether 
an upgrade should install -legacy or not. I guess this either has to be 
special-cased by the upgrade manager or release-noted.
