...in a word, no. I mean I could, but it wouldn't solve the issue as my PPA would have to compile and hold a new version at the same time as the bumblebee repo.
I guess I could write a script to update the package info, then if there is a new version of bumblebee - install it, then overwrite the config file (or at least, use sed to change the lines affected). Or I guess I could just keep my eyes open for the bumblebee package during an apt-get upgrade, and then run a 1 line sed script to update it. With bash, it should be possible to test for distro name (inxi?), and if it's Mint, then execute the sed script. I might play with this if I get time, then fire it at the bumblebee devs/maintainers. It seems like the sort of thing that could form part of the package install
