Re: nouveau modeset no longer works with kernel 4.0 on Power Mac G4
Hi,
I have posted a message on the debian powerpc mailing list recently
regarding the nouveau issues along with creating a bug report for the
nouveau developers to look into. Within the freedesktop nouveau bug
report, a nouveau dev explains why it is failing to work in more recent
kernels.
Post below, link within for nouveau bug report.

As a workaround, i have been able to get it up and running by using an
equivalent x86 vga bios for the exact card that you have (in my case i
have a Quadro FX4500). Not ideal, but gets you running till the bug gets
fixed.
Simply download the equivalent x86 vga bios for your particular card,
save file within /lib/firmware.
In my case i saved the x86 vga bios as quadro_fx4500.fw .
pass the following option to the nouveau module (change the to the
filename as saved within /lib/firmware).
options nouveau config="NvBIOS=quadro_fx4500.fw"
I have used this workaround on vanilla 4.1.2 kernel, it seemed to work
for me on my pmac g5 quad with quadro fx4500 gpu.
As mentioned, not a fix, but a workaround...
Regards,
Peter
