Hallo Jens,

Well, it might be a good idea to write your requests to an international
mailing list in english ...
so let's translate your questions (not a strict translation)

For this to work, you must first use pvcreate to add the LVM's PV
information to your device:
pvcreate /dev/ataraid/d0p1

But this will not help you, as pvcreate checls the device name against a
list of valid devices, and /dev/ataraid is not port of this (at last not
in the way outdated 0.9.1beta5 src I've on this system)

OOTH you should not trust the bios based softraid of any of the consumer
raid devices, it is no hardware raid (not just MHO). If you want to do raid
with IDE devices, I'd suggest using the kernel based MD drivers, and putting 
every IDE disk on it's own channel.
