Few issues with N120

Question

I got a few issues with the N120 netbook that I hope you could help me to sort out.
1.
First the brightness up/down keys. First I gave this fix a go.
http://www.sammynetbook.com/plugins/for … .php?29576
It works but its very unstable for me, sometimes it will get stuck and just turn the screen all the way down and then hang for some time before being able to turn the light back on. The icon will hang on the desktop too. Beside that it occasionally makes gnome panel freeze or really most of the time.
Then I gave .xbindkeysrc a try from the NC10 wiki.
#Brightness up/down
"xbacklight +10"
m:0x0 + c:111
"xbacklight -10"
m:0x0 + c:116
That seems to work fine however it is not binded to the Fn (just binded to up/down arrow) key I am sure I am missing something pretty simple here, but....
2.
Wifi Fn key binding is not working. xbindkeys -k gives me -
"(Scheme function)"
m:0x0 + c:75
Here I am simple not sure what "Scheme function" to use.
3.
I would like to blacklist the webcam just not sure what module to blacklist. I did check for a BIOS option but unfortunately there is none.

Other then these few issues all really seems to work really well. I have only had Arch installed for a week or so (not a lot of time on my hands atm though) but sorting these issues would would make it a 100% for me.
I would appreciate if you could help me out.

1.  My "gadget" is a basic script:
#!/bin/sh
# display brightness script
# author: lswest
usage="usage: $0 -c {up|down}"
command=
increment=5%
while getopts h o
do case "$o" in
h) echo "$usage"; exit 0;;
?) echo "$usage"; exit 0;;
esac
done
shift $(($OPTIND - 1))
command=$1
if [ "$command" = "" ]; then
echo "usage: $0 {up|down}"
exit 0;
fi
display_brightness=0
if [ "$command" = "up" ]; then
$(xbacklight -inc $increment)
display_brightness=$(xbacklight|cut --delimiter="." -f 1)
fi
if [ "$command" = "down" ]; then
$(xbacklight -dec $increment)
display_brightness=$(xbacklight|cut --delimiter="." -f 1)
fi
icon_name=""
if [ "$icon_name" = "" ]; then
if [ "$display_brightness" = "0" ]; then
icon_name="notification-display-brightness-off"
else
if [ "$display_brightness" -lt "33" ]; then
icon_name="notification-display-brightness-low"
else
if [ "$display_brightness" -lt "67" ]; then
icon_name="notification-display-brightness-medium"
else
if [ "$display_brightness" -lt "100" ]; then
icon_name="notification-display-brightness-high"
else
icon_name="notification-display-brightness-full"
fi

notify-send " " -i $icon_name -h int:value:$display_brightness -h string:synchronous:brightness
It uses notify-osd and displays the bar/icon.  If the icon is missing, you will have to copy the notification-* svg files over from the human icon theme.  Just in case you'd like it.
Depends what you want to do with the wireless.  You can just bring the interface down with
sudo ifconfig wlan0 down
Or else you can remove the module with
sudo modprobe -r <module>
