Normally, you don't have to do anything special. If it's the broadcom-wl driver from RPM Fusion, then what you described occasionally happens. Take a moment to list the relevant installed packages...
rpm -qa | grep -e kernel -e kmod-wl -e broadcom-wl | sort
All of that should make sense regarding the version numbers and your kernels. Another thing to try is the akmod-wl version of the driver. Install that and reboot into the new kernel. It should build the kmods for you.
If it's not the broadcom-wl driver you're talking about, then of course disregard the above.
