I tried the Arch32-light package Xyne made, but I may have done something
wrong, so I uninstalled it. Then I found out that, don't know how, my root
password wasn't correct, had to readd gnome-session to > .xinitrc and
resetup pidgin(including pidgin plugin tha twas installed) and Thunderbird.
It is like I just installed all those apps and had to set them up it is
really weird.

I am afraid of tempting that again :) So I thought maybe use mkarchroot -r
/aur/root and setup the pacman.conf to use i686 and such. What do you think,
will this method work good?
