Yes, the rpm format has changed since rhel5/fc5. You will need a more
modern fedora to extract things.

Yes, it's an empty package that simply requires the right kmod for your
currently running kernel.

rpm -qli should provide that info as well.

It means you can:
yum install kmod-wl
and it will download that package and see that it requires the specific
version for your kernel. So you don't have to:
yum install kmod-wl-2.6.35.6-48.fc14.x86_64-5.60.48.36-2.fc14.2.x86_64
which you might note is a bit more difficult to type. :)
