I think I identified the problem.
The TFP410 (dvi chip) is kept in power down state (PD_n pin). I verified it on hardware, the pin is in reset state (0 V) with recent kernels, whereas it is in normal state (3.3 V) with older kernels. I need to dig a bit further to know where is the problem in the code.
Btw, I earlier said the patches I mentioned fixed the DVI output for my beagleboard. But it can be fixed without any patches, by setting CONFIG_DRM_OMAP_NUM_CRTCS=2. Tomi
