Hello!
I have the same graphics card. It works for me on Debian testing with
the following work-around:
https://lists.debian.org/debian-powerpc/2015/07/msg00043.html
I used a PC-VBIOS from https://www.techpowerup.com/vgabios/ and saved it
as /lib/firmware/geforce_6200.fw. I added the following line to the
kernel command line in GRUB and yaboot:
nouveau.config=NvBios=geforce_6200.fw
You may choose the card closest to your card (the same manufacturer).
Assuming you have a 256MB VRAM version:
https://www.techpowerup.com/vgabios/index.php?architecture=NVIDIA&manufacturer=&model=6200&interface=AGP&memType=&memSize=256
If one VGA-BIOS-ROM does not do the job, try another one.
Note that you will need to ssh into the machine to do this, or access
the yaboot and grub configuration files from the installation media in
rescue mode, or install an older version of Debian Linux that uses a
kernel pre-4.0, do the configuration and then update to a newer version.
I am not 100% sure, but I think that Debian 7.5 worked well. Maybe 7.7
still does too. Debian 8.0 already has this issue and cannot be used
without work-around.
If you need more information, just ask.
Good luck!
