Yes,
IIRC, the code force an error when unknown DCB entries are found to make sure
they get reported. I was told to comment the corresponding block of code in nv_bios.c and the server is now up and running with randr 1.2 . I saw a commit on that particular piece of code (4744e5410c27d8bd3c2f92bee4554801639dba29) just after I made the bug report. But xserver still refuse to launch out of the box, I still have to comment the block around ' ErrorF("Unknown DCB 1.4 / 1.5 entry, please report\n");' .
If failing on unknown DCB entries is indeed an intended 'feature', maybe this bug can be closed....
