Hi,

Here is the solution i use to properly prevent a module from loading. I
create a file /etc/modprobe.conf/local and in this file, i write a line
for every module i don't want:

install module_name /bin/true

When the kernel install the module, this line tell the kernel what to do
to install it (here nothing, it simply call /bin/true).

cu.
