Help with kernel / insmod

[elleryjh]

Trying to upgrade to 2.4.21-58.EL (the rpm) the server had a kernel panic.

From the tech who booted the server:

The server was in kernel panic, this is the error that results from the new kernel.
Kernel requires old insmod, but couldn't run /bin/insmod.old: No such file or directory
ERROR: /bin/insmod exited abnormally!

[email protected] [~]# ls -l /*bin/insmod*
-rwxr-xr-x	1 root	 root		13215 Oct 18  2006 /sbin/insmod*
-rwxr-xr-x	1 root	 root		  359 Jun 29  2004 /sbin/insmod_ksymoops_clean*
-rwxr-xr-x	1 root	 root	   144160 Sep 24  2004 /sbin/insmod.old*
-rwxr-xr-x	1 root	 root	   421752 Oct 18  2006 /sbin/insmod.static*

Any ideas on how I should proceed? How do I add insmod.old to the image?
