How to avoid "export in first frame" while making a preloader?

Normally I use getBytesLoaded() and getBytesTotal() to make a preloader with percentage of how much the user has loaded the swf fla. Unfortunately, I have several “heavy” movieclips that use Linkage with the checked options:“Export for ActionScript” and “Export in first frame”. Hence, as I notice, the code with “getBytesLoaded() and getBytesTotal()” would ONLY RUN AFTER those “linkage” moveclips were loaded first. As a result, users have to wait for a while before seeing the loader with loading percentage (as in my program, when I tried to Simulate Download, I saw the loader started from ~80%).
So is there anyway to make my loader appear immediately?
