update:
The problem seems not related to my nova card.
I found out that always the first video-device on the pci-bus is
working, and the second shows the problems.
So it could be some kind of pci-problem.
here is a lspci -vv outout of the system:

perhaps, somebody got a clue on what's going on ?
The next thing what I'll do is to try out a mainboard with 845-PE
chipset...
