There was one! i soldered a bridge - no more problems. The card runs fine at 14 mhz and nearly at 16. In the testing process i came to the conclusion, that in addition to the broken trace the TWGS didn't like Cypress or ISS Sram ICs. luckily i had some UMC branded ones left that worked (only 20ns though).

Grounding might be an issue here. I added a couple of ground wires from the PSU to the ground in slot 3 and one to slot 7. This eliminated a lot of noise and made my system more stable.
