Flat SCM Structure + Continuum = broken module-links on site

We have a flat project structure and we're gradually adding maven support. The layout looks like this:

/masterproject/trunk/pom.xml
/component/trunk/pom.xml
/component/trunk/subcomponent1/pom.xml
/component/trunk/subcomponent2/pom.xml

in out masterproject/trunk/pom.xml, the module is defined like this:
<module>../../component/trunk</module>

Building locally works fine, but when the build is run in continuum, it can't find the module because continuum has its own layout.

The annoying result is, that our <menu ref="module"/> will print a href and text of "../../component/trunk" in the modules menu.

The build output contains this: "[WARNING] No filesystem module-POM available"

How do we get this to work locally as well as in continuum?
