I extracted the following files from neopwn tar.gz and moved them to to a folder "pinject" under /opt/
compat.ko
rfkill_backport.ko
cfg80211.ko
mac80211.ko
wl1251.ko
wl1251_spi.ko

I then wrote a script, named it as on-mod.sh, that contained the following:
#!bin/bash
rmmod wl12xx
rmmod mac80211
rmmod cfg80211
insmod compat.ko
insmod rfkill_backport.ko
insmod cfg80211.ko
insmod mac80211.ko
insmod wl1251.ko
insmod wl1251_spi.ko

when i run this, the wl12xx is unloaded (since i cant see any wireless networks in my select connection panel), however i get the following errors:
insmod error inserting 'compat.ko': -1 invalid module format
insmod error inserting 'rfkill_backport.ko': -1 invalid module format
insmod error inserting 'cfg80211.ko': -1 invalid module format
insmod error inserting 'mac80211.ko': -1 invalid module format
insmod error inserting 'wl1251.ko': -1 invalid module format
insmod error inserting 'wl1251_spi.ko': -1 invalid module format

What am i doing wrong?? I can work my way around linux and have done a bit of work with aircrack, but this has me stumped.

I have *NOT* used any of the other files from the neopwn tar.gz. The following files were also present in the folder:
kernel-power_2.6.28-maemo40-wl1_armel.deb
kernel-power-flasher_2.6.28-maemo40-wl1_armel.deb
kernel-power-modules_2.6.28-maemo40-wl1_armel.deb

I just need packet injection to work without the whole neopwn suite... Any help here??
