I *HATE* that.  My solution was to scriptify the swapping of different 
/etc/XF86Config files.

I know I should use a cmd argument for xinit, but it's a pain in the arse for a 
box with only
one X user.

  $ls /usr/local/bin
        XF86Config-4_640x480            -> XF86Config-4_xinerama
        XF86Config-4_800x600            -> XF86Config-4_xinerama
        XF86Config-4_dualhead           -> XF86Config-4_xinerama
        XF86Config-4_radeon             -> XF86Config-4_xinerama
        ...
        XF86Config-4_xinerama

  $cat /usr/local/bin/XF86Config-4_xinerama
        #!/bin/sh
        CONFIGURE_SCRIPT="/usr/local/lib/.XF86Configure-4"
        echo $0, $1;
        if [ `whoami` != "root" ]; then 
            su -c "$CONFIGURE_SCRIPT $0 $1"
        else
            $CONFIGURE_SCRIPT $0 $1
        fi
