I am trying to get this system to work with Debian. When I run lspci the video card is identified as:
I currently have a fresh install of Jessie with the MATE desktop. I was able to successfully boot to the DE using the nouveau.modeset=0 yaboot parameter, but the desktop has abnormal psychedelic colors.
I did some googling and found the page at Power PC Liberation (

https://lists.debian.org/debian-powerpc/2016/02/msg00025.html) and I followed all instructions. Thank you for the kernel, Peter!
However, unfortunately, after rebooting to the "test" yaboot option, I don't get a login prompt any more. Instead I get an empty gray screen. Are there any next steps that anyone can recommend? I can still boot to the abnormally-colored DE using kernel 3.16 using the "Linux" yaboot option. Thanks in advance for any guidance you can give me.
