After upgrading to =x11-base/xorg-server-1.13.0-r1 on my iBook G4, and then remerging all x11 drivers, the X enviroment stopped working.
Short description: (EE) No devices detected.
Long description: see the attached Xorg.0.log file.
I have downgraded to =x11-base/xorg-server-1.12.2 it works again.
The same problem here on my laptop with stable amd64 and VIDEO_CARDS="intel".
Going back to xorg-server-1.12.4 solved the problem.
I have no problem on x86 and amd64, both nouveau and intel
Same problem here on PowerMac G5 running ppc64 with Radeon9800XT card.
Same problem with latest stable 1.13.1

I'm having the same problem on my PowerBook G4, see bug 448424.
A few things to note here:
1. We need to move to KMS in order for this to work, even on PPC! Make sure you have the KMS drivers built and that the radeonfb driver isn't running.
2. I found that specifying the BusID for my Radeon card in an xorg.conf fixes this specfic problem. Apparently there's a regression in the device finding code.
3. As an aside, for best performance, also turn off vsync in your xorg.conf, it runs terribly on PPC with vsync on.

That worked for me. Thank you.
You should make sure that upstream is aware of this problem, best check https://bugs.freedesktop.org/ if a report already exists and create one if not.
On my Mac Mini G4 the KMS drivers are near unuseable, with very frequent crashes and colour glitches. See also https://bugzilla.redhat.com/show_bug.cgi?id=813949

That is a different issue, please don't mix the two in this bug.
