Vga switcheroo reports that can handle the card. The problem is a
conflict with the method called to turn off the card at system startup.

Try to disable the bumblebee "turnoff on startup" script, it seems that
it's not turning off the card correctly, that's why you see this kind of
message:
 FATAL: Error inserting nvidia_current
(/lib/modules/2.6.35-30-generic/updates/dkms/nvidia-current.ko): No such
device

Vga-switcheroo will work when the card is on and usable (nouveau driver
loaded).
The workaround to use vga-switcheroo is to unload the nvidia driver,
load the nouveau driver, call OFF on vga-switcheroo. To turn the card on
the process is exactly tho opposite: call ON on vga-switcheroo, unload
the nouveau module, load the nvidia module.
