OK I managed to fake the 1280x800 resolution setting by "tuning" the
1024x768 BIOS mode. 

The next step is how do i get a dual head Xinerama setup with the panel
and a CRT ? At the moment it shows the same picture on both displays
(with the difference that on the panel the cursor is not visible).
The wanted Xinerama setup is CRT (PipeA) at 1280x1024 and the panel
(PipeB) at 1280x800, is that possible.
