I have a Z12 with 10.10 and a patched bios for static switching,
though I think this isn't required anymore. 

To get the switching working well, install Adam's upstart script but
change it to the attached file. Ubuntu/Debian handle the GL library
switching through their alternatives system.

Booting into speed works for me, I have to boot then reboot to get
stamina to work. Though I think that's fixable with just an X restart.
