[NV94] no HDMI output, xrands claims DVI-D-1 disconnected

Hi,
Using SuSE-Linux, my HP EliteBook 8730w does not manage to produce output on
its HDMI plug. The VGA plug works. HDMI works when booting MS-Windows 7 Pro
on this machine, which I tested with a 1920x1024 HDMI TV and a 1280x1024 DVI
monitor. I can plug the HDMI cable into a Raspberry Pi and it works. So the
cables or monitors should not be at fault.
The graphics card is NVidia Quadro FX 2700M, reporting itself as NV94
(NV50 according to http://nouveau.freedesktop.org/wiki/CodeNames/).
Initially I observed this issue in SuSE-Linux 11.4. In the hope for a fix, I
upgraded to SuSE-Linux 13.1 yesterday, but it persists.
xrandr always[*] reports two disconnected DVI-D plugs:
Screen 0: minimum 320 x 200, current 1920 x 1200, maximum 8192 x 8192
LVDS-1 connected primary 1920x1200+0+0 (normal left inverted right x axis y axis) 367mm x 230mm
[...]
DVI-D-1 disconnected (normal left inverted right x axis y axis)
DVI-D-2 disconnected (normal left inverted right x axis y axis)
VGA-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 338mm x 270mm
Xorg.0.log (attached) always contains:
(II) NOUVEAU(0): EDID for output DVI-D-1
(II) NOUVEAU(0): EDID for output DVI-D-2
(II) NOUVEAU(0): EDID for output VGA-1
I don't know why it reports DVI-D instead of HDMI, or why there appear to be 2
DVI-D devices -- perhaps it's a dual-link HDMI connector?
I have tried:
- Configuring HDMI via xrandr (see below)
- Booting with and without HDMI cable connected
- Hotplugging HDMI
I've not tried installing the binary NVidia driver.
[*] When I tried the monitor the first time, both DVI-D plugs where
reported as connected once and only once, yet with no mode information. I've
not seen that happen a second time.
Reading some net.wisdom https://bbs.archlinux.org/viewtopic.php?pid=975209
I tried manual activation as follows:
$ xrandr --addmode DVI-D-2 1280x1024
$ xrandr --verbose --output DVI-D-2 --mode 1280x1024
crtc 1: 1280x1024 59.9 +0+0 "DVI-D-2"
xrandr: Configure crtc 1 failed
crtc 0: disable
crtc 1: disable
screen 0: revert
crtc 0: revert
crtc 1: revert
Some user mentions a perhaps similar issue with SuSE Linux on a HP machine,
however his is a hybrid Intel + NVidia graphics machine, mine isn't:

Bug #54512 is different too, there the drm module got some EDID response.
Attached logs are from SuSE 13.1, which I installed by removing 11.4. (This
time I booted into safe mode for an unrelated reason).
