Nvidia Arch-style instaler

Question

Last time I created (for my friend, I haven't nvidia card) Nvidia installer in Arch style (no magic, only regular PKGBUILD).
Install instruction (strange, because nvidia install script overwriting some xorg files and some files are not be removed after uninstall):
0) Exit with X
1) Uninstall driver (pacman -R nvidia) and change all modification in config files (/etc/rc.conf, /etc/modprobe.conf OR /etc/modules.conf /etc/X11/XF86Config OR /etc/X11/xorg.conf)
2) Install and uninstall this version nvidia driver (with -f option)
3) Uninstall and install xorg package
4) Install this driver (with -f option, backup was created) and enjoy.
For my friend everything works fine (GForce MX-400) but please be carefully. Please hack it when something wrong occured.
Greetings,
Miroslaw

An nVidia installer already exists in Staging.
