Kernel log (dmesg)

Hi,

I have been running Debian Linux on a Apple PowerMac G4 "Quicksilver" (Model:
M8493) with the following main hardware specifications:

- PowerPC G4 7450, 867 MHz
- 1GB main memory
- nVidia GeForce GeForce2 MX/MX 400 (NV11) AGP video adapter

Software environment:

- Debian Linux PowerPC unstable
- Kernel 3.4.4 (from Debian experimental)
- nouveau X.org driver 1.0.1
- libdrm: 2.4.33
- mesa: 8.0.3

Problem description:

When using nouveau, the video adapter permanently turns off the attached
display through DPMS. This cannot be reversed and I do not get back video until
I reboot the machine by logging in through SSH. I can neither switch to a
virtual text console using <Ctrl>+<Alt>+<F1..Fn>.

The video output is fine when preventing X from starting and using just a
virtual text console (KMS works fine as well).

xrandr does not any displays attached, see attached logfiles and xrandr output.

I'm attaching the following files:

- kernel log (dmesg)
- Xorg.0.log
- lspci output
- xrandr --verbose output
- vbios.rom (cp "/proc/device-tree/pci@f0000000/NVDA,Parent@10/NVDA,BMP"
~/vbios.rom)

If you need any further input, please let me know. The machine is a sole test
machine, so I'm happy to try any code from git or run any quirky code.

Cheers,

Adrian
