So the console is working.

X has a problem. In your place I would try with an xorg.conf like the following:
---
Section "Device"
    Identifier  "Configured Video Device"
    Driver      "nouveau"
    Option      "Monitor-TV-1"  "Configured Monitor"
EndSection

Section "Monitor"
    Identifier  "Configured Monitor"
    Option      "Ignore"        "true"
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Device      "Configured Video Device"
EndSection
---
The idea is to disable the chip internal TV output that is not connected.

In addition you could add the kernel command line option (with the
same meaning):

video=TV-1:d

but since you can see the console, it's probably not necessary. The
file to edit is /etc/yaboot.conf, and afterwards you have to run;
'sudo ybin -v'.

I've tried this on a PowerMac G5 with a similar - probably identical -
controller.

Yet another thing to try - in case the above does not help - is to
create the file /etc/modprobe.d/nouveau.conf:
---
nouveau noaccel=1
---
But this disables the acceleration.
