on bug 87856
from kristof
Hello,
I've successfully install Debian Jessie on iMac G5 revC (iSight)
Facing same issue, I've followed these instructions here in order to downgrad
mesa packages :

Workaround :
1) Jessie fresh install graphics results (no firmware non-free installed), able
to log in graphic session :

dmesg | egrep 'drm|radeon' complains about microcode :

2) then install it with non-free firmware :
