Ok, I archived enlightment! ;-)

As far as I understand (by taking a quick look at the code), they only
introduced a new type because the domain search list is compressed
using a special technique described in RFC1035. This technique uses
pointers to prior occurrences. In the RFC3397 using the techique is a
MUST, but because it only saves space it works without using it too.
In the configuration file and the resolv.conf file it's always a
string.

I will try to use the 3.1 release of the dhcp3-client and we will see,
if this solves my problems. Thanks for the hint!
