multiple modules using before_body_end

Question

I created a module that uses the "before_body_end". On some pages a second module also uses before_body_end. Is there a way to dermine the order ?

example:

<div class='mymodule'></div>
<div class='3rdpartymodule'></div>
</body>

to :

<div class='3rdpartymodule'></div>
<div class='mymodule'></div>
</body>

An addendum to @marius' answer, rather than place the core dependency in a core override you can state the dependency in your own module so that disabling it also disables the dependency:

<?xml version="1.0"?>
<config>
    <modules>
        <YourCompany_YourModule>
            <active>true</active>
            <codePool>community</codePool>
        </YourCompany_YourModule>
        <Mage_Customer>
            <depends>
                <YourCompany_YourModule/>
            </depends>
        </Mage_Customer>
    </modules>
</config>

Answer 2

in the layout XML of your extension add the after attribute to the block declaration.

<reference name="before_body_end">
   <block type="your/module" name="your_module" after="-" template="your/module.phtml"/>
</reference>

As long as the other extension doesn't do the same you should be good and your block should always be inserted last.

Make you module depend on the third party module. Add this in app/etc/modules/[Namespace]_[Module].xml

<depends>
    <Thirdparty_Module />
</depends>
