Sounds pretty simple to me.  If you are using lilo, then you might not 
be rerunning lilo after installing the new kernel.  Also, after 
installing a new kernel you need a new initrd image.  Your unresolved 
symbols problem is because you are trying to load the ext3 module from a 
2.4.7-10 kernel in the 2.4.9-13 errata kernel.  The general answer here 
is that there is significant documentation on what must be done to 
upgrade a Red Hat kernel.  Read it.
