Hi Markus,
It's not entirely clear what you want to do with the pyramids, so on the off
chance you want to serve them via a web-map I'll point out that WCS (Web
Coverage Service) servers usually include the ability to perform this magic
too.
deegree does it here: https://wiki.deegree.org/deegreeWiki/RasterTreeBuilder
GeoServer here - http://geoserver.org/display/GEOSDOC/Image+Pyramid (the
documentation is a little dated in places because they're transitioning
documentat systems - asking questions on their excellent mailing list helps)

I imagine the other WCS servers can also do it but I don't know anything
about them. In the case of GeoServer, you can have it ouput as a KML layer
with WMS (Web Map Service) using the SuperOverlays that Barry mentioned:
