kernel log with nouveau.debug=trace and drm.debug=0xe

Hardware information: 
CPU: Intel Core2 Quad Q9400 
Graphics card: GeForce 9600 GS (output: 1x VGA, 1x DVI, 1x HDMI)

Version information
Distro: ArchLinux x86_64
Linux Kernel: 3.16.3 (compiled with CONFIG_DRM_NOUVEAU=m)
libdrm: 2.4.58
Mesa: 10.3.0
xf86-video-nouveau: 1.0.11

Issue: 
TV connected via HDMI reports "no signal" when system is booted. During boot
the HDMI display output works fine, but when selecting the kernel to load in
the bootloader the TV starts reporting "no signal". As the output is already
lost before any X

What I tried so far:
- Booting with HDMI cable connected
- Booting with HDMI and VGA cable connected
- Booting with no cables connected, following hotplugging HDMI and VGA
None of above actions resulted in a fix or any other results with the display
via the HDMI port, the display of the VGA port always is functional.  

Other findings:
- The NVIDIA proprietary drivers HDMI display output works fine with the TV
- Graphics card is GeForce 9600 GS, according to the CodeNames this should be a
NV96 (G96), though when quering the system it reports as G94. This seems to be
conflicting. 05:00.0 VGA compatible controller: NVIDIA Corporation G94 [GeForce
9600 GS] (rev a1)
- While having the HDMI and VGA connected, querying the status of all ports
report that the HDMI and the VGA are connected::
-- ~: for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n
"${con#*/card?-}: "; cat $p; done
-- DVI-I-1: disconnected
-- HDMI-A-1: connected
-- VGA-1: connected
