Specifying a `KernelDriver` containing `_` or `-` in the `nvidia` driver section of `/etc/bumblebee/bumblebee.conf` causes `optirun bash` to fail with

    [ 533.997079] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) Failed to load module "nvidia352" (module does not exist, 0)

    [ 533.997196] [ERROR]Aborting because fallback start is disabled.

if `nvidia_352` or `nvidia-352` has been specified. Futhermore this is impossible to debug without massive loss of sanity if `optirun` doesn't tell where configuration options have been picked up from if a critical error occured. `grep -r 'nvidia352' /etc/bumblebee/` returns no result.
