As advices in this Fedora 17 feature:
Some directory /sbin/ /bin and specially /lib /lib64 will not be used
the same as previously, and will be moved to the related /usr
This change include the /lib/modules directory that I expect, will be
moved as /usr/lib/modules
Here are some package to be tested for that case:
At this step this requires the akmod-foo package to be recreated with
the modified kmodtool.
So the only one already provided (akmod-nvidia) is also problematic as
you may need to rebuilt the kernel without debug. (it should work with
f17 xorg-server that been said).
