These options need to reference the monitor identifier you've defined, e.g.

  Option "Monitor-VGA" "Monitor-VGA"

Though in your case that's a little confusing since you've given your monitor 
identifiers the same name as the intel option.

Once the intel driver knows which monitor section to look at for a given 
monitor, it can honor the "LeftOf" etc. options.

Here's my xorg.conf for reference (note that this is also documented in the 
man page and at intellinuxgraphics.org).
