Xorg.0.log

I have an ancient computer with a FX 5200 card which is played to an old TV via
composite output. It has been working for ages, until I upgraded the system
(debian) and now when I start X, the tv image goes off.

This setup is using KMS, and IIRC newer kernels had the same problem on module
load. I downgraded the kernel to 3.11.2 and now the framebuffer is working 
fine again (with at least 3.11.6 and newer kernels it's a no-go). But when
starting X, the image is gone and the log tells:
