I don't see it in /usr/share/kbd/consolefonts, so I guess that means yes. Maybe you can see if you can pull an old kbd package from the Arch Rollback Machine and stick the layout in there (and maybe the font too... not sure how that works).
@cfr, you know you can simply use [[ -f /etc/profile ]] && . /etc/profile instead of the if/then statement. It will work either way, but I use the one liner because it makes my .xinitrc look a little cleaner.
