You don't understand my problem fully. I don't want to run one X-Server
with my Hercules and my S3, but actually two X-Servers, one for the Hercules
and one for the S3.
But i think, i know the source of the problem, but that doesn't help me much
in the way of a solution. The culprit, i think is XS3, which is derived from
Xfree1.2, which isn't able to handle virtual Terminal support.
