i could resolve the issue, thanks to all who helped :)
the problem was that there is indeed a partition the the array's and the
partition map was not created. i did use the gentoo live cd, but on an
installed gentoo system the partition maps are not created out-of-the-box
by udev either

anyway, thanks again :)
