First, run

rpm --rebuilddb

This will run a consistency check on the RPM database. Then run

rpm -q fedora-release

Your yum error suggests that you have fedora-release-16 installed,  
irrespective of what your motd announces. If so, mount the F17 install  
media, go into the Packages/f directory and run

rpm -UvhF fedora-release*

to manually update your fedora-release package to 17. The run

rpm -q kernel

This will list all the kernel packages you have installed. Presuming that  
you have indeed booted an older F16 kernel, after running

rpm -e kernel-<version>-<release>

naming the specific F17 kernel package that croaks when you try to boot,  
this should remove it.

After which you should be able to yum update to the most recent kernel  
package, and any other packages that need to be updated.
