radeonhd and xorg issues on powerpc p5020 and G5

[luigi burdo]

hi michel,
without xorg conf on cyrus+ p5020, and g5 quad i have only the black screen with pulse cursor. i need to made it and put in etc/X11/ or not desktop at all.

about modeset=0 on both cards:
yes i know is normal dont have video but i think the more strange is have the opposite compared the kernel options . with kernel radeon. modeset=0 and nouveau.modeset=1 look like xorg understand to activate the radeon and deactivate the nouveau .
and this make the system stalling without any way to recover.

about radeonsi, will check  on 7750 too and report.
for now 4xxx,5xxx,6xxx can say are running on ppc system with 3d too , yes many endianess on egl and egl2 colors not right and some creazy texture on some games but ... running ;-)

ciao
luigi
