To be a bit more precise: The situation with kms is rather unsatisfying
(this is not an opensuse problem but a design-problem with Linux
module handling).
Here's the receipt for the generation of unhappy users:
1 If you want to add a module parameter for a specific module, you
  can do so at kernel boot time. In that case, it has the format
  <modulename>.<parameter>.
2 If you specify an invalid, i.e. non-existant parameter name, the module
  will not load.
3 Make KMS a compile time option with a parameter name that only exists
  if the KMS option has been compiled in.

Now someone needs the option to disable KMS and adds that line to the
kernel boot options. In case your kernel has been compiled with KMS,
things go as expected. If, for whatever reason, you change to a kernel
that has KMS disabled, the module will *always* fail to load at all.

Fantastic design.

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
