Is the machine still booted?

If so, look at the output of 'rpm -qa | grep kernel'

Download the RPMs that are referred to by the list.  Then "rpm -F" the
RPMs you downloaded.

If you're brave AND lazy, do the following:
# rpm -qa | grep kernel | egrep -v 'utils|pcmcia' > list.txt
# rpm -e `cat list.txt`
	// --nodeps may be required
# yum install `cat list.txt`
	// Some editing of the list may be required; version numbers
	// may need to be removed.

If the machine is not booted, you can work off of a variation of the
following process:
     1.  oot up off the install CD, and let the installer start the
        network and mount the volumes for you.
     2. Get your bearings -- "df -h" or "mount" should tell you were
        it's the system is mounted.  It's usually /mnt/sysimage, and the
        rest of the stuff is the install CD.
     3. Get your bearings some more -- check the network setup by typing
        "ifconfig"
     4. Change into your system with chroot.  The command is usually
        something like "chroot /mnt/sysimage", and then perform the
        above steps.

Please note that I'm outlining the process here and working from
memory.  There may be some quirky little details that I've left out.

I hope this helps!
