I get the error message "(EE) No devices detected" on a Mac G4 (PowerPC chip) with an "ATI Radeon Mac Edition 9200" in it. The software involved is: Gentoo Linux xorg-x11 7.2 xorg-server 1.2.0-r3 xf86-video-ati 6.6.3 The kernel gives messages indicating it sees both the card and the attached display. X11 fails to see the card however when using the radeon driver. (It had worked previously, probably with 7.1.) The best I can get out of X11 is using the fbdev driver. You can find a brief discussion of the problem, as well as a Gentoo developer's recommendation that I send the problem "upstream" to you at the URL associated with this bug, namely, http://forums.gentoo.org/viewtopic-t-566015.html A folder with the Xorg.0.log, xorg.conf, etc., is under http://www.pdc.kth.se/~mike/PPC_X11/
It's probably related to the card being on PCI domain #1. Some ideas for helpful things you could do: * Isolate the change that caused the regression with git-bisect. * Try the xserver GIT branch pci-rework to see if it's fixed there.
This is probably fixed with current xserver and driver, at least with KMS enabled.
