I assume the monitor is correctly detected as being attached on DVI-D? Assuming
this is so, this is not expected to work currently on your particular card as a
separate TMDS chip needs programming up, so there's going to be some work in
getting it going.

Do the VGA and DVI-A connections work as expected?

Yes VGA and DVI-A works well. I tried only booting with the screen connected at
boot, but no "hot plugging" and detection while xserver is runing.
Connected with DVI-D the screen stay on but shows only black. The driver
detects the right mode.

If only the DVI output is used at boot, does it work with nouveau in
non-randr12 mode or the nv driver? If it does:
git clone git://people.freedesktop.org/~airlied/radeontool
git checkout origin/nvidia
make

then run "./radeontool regs > logfile", both when in the working non-randr12
state, and (if possible) remotely over ssh when in the broken randr12 state,
and attach the logs to this bug.

If nv / non-randr12 doesn't work, but console mode does, comparative
working/non-working dumps would still be useful.

radeontool regs output - different configs

dvi-d works with nv and nouveau no randr12 when the screen is connected from
boot.
this is the dvi-d chip on the card. I'm not sure if I2C is connected but in the
datasheet is a description of registers.

I think something went wrong, that log is filled mostly with zeros and some
random stuff.

While bringing up the SIL may be eventually interesting, we first ought to be
able to bring up a display by not breaking the existing setup (as in the
non-randr12 case) -- radeontool dumps should let us do this.

Unfortunately the radeontool dumps you provided are broken, as you have many
nvidia pci devices, and radeontool is somewhat stupid :)

To fix this, change radeontool.c line 501 from
radeon_cntl_mem = map_devince_memory(base,0x700000);

to

radeon_cntl_mem = map_devince_memory(0xe4000000,0x700000);

recompile, and dump again (logfile_nouveau and log_nouv_r12 being the
interesting ones)

If you feel like having a poke at some registers, I've a couple of candidates
-- CR59 and 0x6808c0. What this means in practice, is running *without* the
comment 9 hack, and trying (via ssh) all four combinations of:

./radeontool regset C0:59 M        where M is 0 or 1
and
./radeontool regset 0x6808c0 N     where N is 0 or 0x100

It may not do much, but at least we can discount them afterwards :-)

Please test whether it now works with an unmodified copy of the latest code in
git. If it does, testing whether changing between CRTC 0 and 1 with "xrandr
--output DVI-D-0 --mode something --crtc n" works would be a good additional
test.
