I tried install the VirtualBox (VirtualBox-3.1-3.1.2_56127_rhel4-1.i386.rpm ), but failed

ERROR:

Dmesg message:

I did try force the instalation of vboxdrv
--------------------------------------------------------------------------------------------------------------------
/sbin/modprobe vboxdrv
FATAL: Error inserting vboxdrv (/lib/modules/2.6.9-78.0.17.ELsmp/kernel/misc/vboxdrv.ko): Invalid module format
----------------------------------------------------------------------------------------------------------------------

My host system is:
-------------------------------------------------------------------------------------------------------------------
Red Hat Enterprise Linux ES release 4 (Nahant Update 7)  32B
uname -r
2.6.9-78.0.17.ELsmp
-----------------------------------------------------------------------------------------------------------------------------

I also instaled the dkms package, and all gcc software are the same version of kernel build.

So I need help to solve this issue.
