How to pass parameters to kernel modules

After some extra research I've found out that Ubuntu uses modprobe.d
instead of modules.conf

So for anyone interested in how to pass parameters to boot up modules,
you just have to edit the file
/etc/modprobe.d/options

and add the needed lines.

For me I added:
options sonypi camera=1
options meye gbuffers=32
options video_nr=0
options forcev4l1=1

and the camera works fine after a clean boot.

Cheers,
