Did you build your new kernel starting with the same options your original kernel was built with? They may be available in /proc/config.gz. They may also be stored under /boot somewhere, as config-kernelname. Kernel settings can drastically alter the way the kernel works so, if you don't build the kernel with the right options, the module won't match the kernel, and the kernel will rightly refuse to load it.

Code:
modprobe config # might not be necessary
gunzip < /proc/config.gz > .config
make menuconfig

mk_kernel

mk_kernel(1M)															     mk_kernel(1M)

NAME

       mk_kernel - load a kernel configuration from a system file

SYNOPSIS

       path_name] system_file]

DESCRIPTION

       reads  configuration information from the system file (see system(4)) and applies those changes to a kernel configuration (see kconfig(5)).
       performs a function similar to that of but has some semantic differences in order to preserve compatibility with previous  releases.   will
       build a new kernel executable only if needed to effect the requested changes.  may reuse existing kernel executables when possible.

   Options
       recognizes the following options.

       Specify the target kernel path.

		 If  the target kernel path specified is changes are applied to the currently running kernel configuration.  They will take effect
		 immediately if possible; otherwise, they will take effect at next boot.

		 If the target kernel path specified is of the form changes are applied to the	saved  kernel  configuration  named  config.   The
		 changes will not take effect at next boot unless that saved kernel configuration was already marked for use at next boot.

		 If  the target kernel name is a single word containing no slashes, that name is used as the name of a saved kernel configuration.
		 The changes are applied to that saved kernel configuration.  The changes will not take effect at next boot unless that saved ker-
		 nel configuration was already marked for use at next boot.

		 If  the  target  kernel  path is not one of the forms specified above, then exits with an error.  Other locations for kernel exe-
		 cutable files are no longer supported.

		 If the option is not specified, the changes are applied to the kernel configuration called The changes will not  take	effect	at
		 next boot unless that kernel configuration was already marked for use at next boot.

       Specify the HP-UX system description file.
		 If this option is not specified, the system file is used.  For details see system(4).

       Verbose mode.  (Has no effect; retained for backward compatibility.)

RETURN VALUE

       returns 0 upon normal completion; it returns 1 if an error occurred.

DIAGNOSTICS

       Messages  and warnings are sent to Messages from and other commands are displayed when invoked from Errors cause to halt immediately; warn-
       ings allow the program to continue.

EXAMPLES

		     Uses the default HP-UX system description file
	      The changes are applied to the currently running kernel configuration, marked to take effect at next boot.

		     Uses the system description file

		     Uses the system description file

WARNINGS

       Do not manually modify the contents of the kernel configuration directories.
