This task depends upon
is not a fatal error. you can run X without this
xf86EnableIOPorts: X.org does this on startup in case a driver needs it. It fails because X runs unprivileged. The intel driver doesn't need this.
/dev/fb0: intel driver doens't need that, you don't have permission because of unprivileged mode
old probe methods: has been around for years
VGA arbiter: probably because of unprivileged mode
Only error that makes any sense in your bugreport is the error about backlight support.
