The problem with the nvidia driver, at least with edge, is the way the
package linux-restricted-modules is setup.

First it (lrm-manger), until modified, "builds" the restricted module
binary directory /lib/module/{Kernel version}/volatile while ignoring
your configuration settings in "/etc/default/*" and builds the kernel
module table from this.

  Sounds like a workable solution doesn't it. EXCEPT for the problem of:

    The resulting "binary only" modules "nvidia"(nvidia.ko) and
"nvidia_legacy"(nvidia_legacy.ko) have the SAME internal kernel module
ID of "nv" and since "nvidia_legacy" comes LAST that's the one the
module tables point to, so that the one the kernel tries to load when a
request for "nv" comes along.

And after a system reboot it (lrm-manger) does obey the setting
in /etc/default/ so "nvidia_legacy" may not even exist NOW.
  {-: note there is even more parts to this little problem. :-}

HUM. where do I report this BUG that I've had to fix each time
linux-restricted-modules-common gets upgraded?
