how to insert fuse module into linux kernel

view story

http://stackoverflow.com – my os is centos kernel is 2.6.18-92.1.17.el5xen. fuse version is fuse-2.7.4 I compiled it like this: ./configure --enable-kernel-module --with-kernel=/usr/src/linux make && make install then "modprobe fuse",but it warned like this: FATAL: Error inserting fuse (/lib/modules/2.6.18-92.1.17.el5xen/kernel/fs/fuse/fuse.ko): Operation not permitted but I did it as root. and another way to install it : /sbin/insmod ./kernel/fuse.ko and i got : insmod: error inserting './kernel/fuse.ko': -1 Invalid module format is there anyone who can help me?
