For some reason, it looks like you boot kernel 2.4.18-0.8a, but the
installed modules are actually for 2.4.19-4a.  Since you have the
modules installed for this one, you probably have the 2.4.19-4a kernel
as well, but the symlinks and/or the yaboot.conf file are wrong.
Under this assumption, here is my take at fixing the problem (which is
by the way kind of a wild guess).

Check /etc/yaboot.conf and see what is the image that you boot by
default.  You should see something like this:

    default=<some string>

and later on:

    image=/boot/vmlinux
            label=<some string>
            root=/dev/hda14

or

    image=/boot/vmlinux-2.4.18-0.8a
            label=<some string>
            root=/dev/hda14

In the first case (the image being /boot/vmlinux), which is the most
probable, make sure that you have the files

  vmlinux-2.4.19-4a
  System.map-2.4.19-4a

as well as the following symbolic links:

  vmlinux     pointing to vmlinux-2.4.19-4a
  System.map  pointing to System.map-2.4.19-4a

In the very unlikely case that you do not have those files
(vmlinux-2.4.19-4a and System.map-2.4.19-4a that is), install the
kernel-2.4.19-4a.rpm from the (YDL 2.3) Install CD and then create the
symlinks.

Once you have this configuration in place, reboot and you should be
back in business.

In the second case, i.e., when you have
image=/boot/vmlinux-2.4.18-0.8a for your default label in
/etc/yaboot.conf, replace this line with 

    image=/boot/vmlinux-2.4.19-4a

and then run

    ybin -v

and then reboot.

Of course, make sure that the files vmlinux-2.4.19-4a and
System.map-2.4.19-4a are present in /boot, as above.

Hope this helps,
Stefan
