Making an ATI Radeon X1900 PCIe work on a G5/Quad (or can I?)
Hi Everyone,
I'm having troubles making an ATI Radeon X1900 PCIe work on my G5/Quad.
It is the G5 MacEdition (and it works with Mac OS X, tested).
With linux, the computer works, but no luck with the video: it is frozen
on the open firmware boot message end (early kernel boot).
Of course, I tried also with "video=ofonly" but the kernel doesn't seems
to take the option into account. For the relevant lines of my dmesg log:
boot:
[...]

after that nothing on the screen (except: smp_core99_probe,

Later in the boot process:

At last, the drm parts:

If it matters, here are some parts of the Xorg.log:

Fatal server error:

I compared with my Mac Mini G4: the difference being that with the G4,
and Radeon R280, it doesn't care about being unable to access BIOS
signature. But since even the console doesn't work properly, I am not
sure it matters yet.
I'm on regular testing, up to date.

I left the old nVidia card in a secondary PCIe slot, but I don't think
it matters, since the kernel don't try and access the secondary card.
I am ready to do some testing if requiered, and if someone wish to help.
Best regards,
