Of course, you can fix all this stuff by executing this ;^)



#!/bin/bash
# Temporarily fixes existing modules to contain the GPL symbol
#

TMPF=/tmp/Abradabrca
VER=`uname -r`

cat >${TMPF}.c <<EOF
#define __KERNEL__
#define MODULE
#include <linux/module.h>
MODULE_LICENSE("GPL");
EOF
gcc -Wall -O2 -c -o ${TMPF}.o ${TMPF}.c
for x in `find /lib/modules/${VER} -name "*.o"` ;
    do echo $x ;
    cp $x /tmp/x.o ;
    ld -r /tmp/x.o ${TMPF}.o -o /tmp/y.o ;
    cp /tmp/y.o $x ;
 done
echo "Fixed!"
rm -f ${TMPF} /tmp/x.o /tmp/y.o

Don't you love it when somebody undoes all this "lawyer" stuff!
