Many thanks for your answer, moreover as an IBM expert who cares about opensource software for pSeries... born to be AIX ;-)
 
I found such problems with Debian Xorg, and would try to go back to Xfree86, even I don't think it would solve.
 
Btw, I didn't manage to start the 8bit 640x480 X-server either, because even using video=matroxfb append when booting with kernel including all framebuffer drivers, I always got an error.
If needed, I could post those logs too.
 
About your pci-rework project, I'm braveheart to test anything could solve my 1-month problem!!!
I also bought an used ATI rage 128 pci mac on ebay to try and solve it, but as far as you told, there's no drivers issue but bus and addressing problem. 
Just, let me know where to find more infos about your this branch, and please a small guide how to compile/configure/make stuff & drivers on ppc64. I always had problems on such architecture... :-S
 
Thank you very much for a brand new hope
 
Valerio.
