How did you build the module?
Modules compiled for one version of the kernel cannot be inserted in another
version. Generally you got this error "Invalid madule format" when you
there is a mis-match between running kernel and kernel-source versions. Here is
an URL on how to build a kernel module for 2.6 kernels

Subject: Re: insmod: error
inserting
let me tell the sequence
of step I followed before I got that error :
(1) I compiled the kernel with the CONFIG_B44=m option
(2) then I booted with this new kernel 2.6.18
(3) at his time lsmod |grep b44 showed b44 (that means module loaded at boot
time)
(4) then , I removed the module : modprobe -r b44 (at this point I lost
the network connection)
(5) then I took b44.c and b44.h from drivers folder of the kernel and compiled
them seperately (away from the kernel) -> this compiled successfully
(6) insmod b44.ko gave me those errors !!!
Any clue , why ?
