Title:
  [xorg-edgers] optirun tries to load driver with specified name
  ignoring _ and -

Status in Bumblebee:
  Unknown
Status in bumblebee package in Ubuntu:
  Confirmed

Bug description:
  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.

  The specified module exists as shown by `modinfo`:

      $ modinfo nvidia_352
