No or broken 3d-acceleration with Jaunty on ibook/powerpc

[David Hedberg]

Powerpc port of Jaunty, installed with the beta-iso and updated today 2009-04-03, seemingly fails to initialize proper 3D-acceleration. glxgears runs with low fps (around 60), and also with a blue tint.
Compiz-manager aborts with:
Software rasterizer detected, abortingaborting and using fallback: /usr/bin/metacity

2D and xv seems to work fine. I have also attempted setting UseFBDev to false in Xorg.conf with no difference.

Possibly relevant section from Xorg.0.log:
(II) RADEON(0): [DRI] installation complete
(II) RADEON(0): [drm] removed 1 reserved context for kernel
(II) RADEON(0): [drm] unmapping 8192 bytes of SAREA 0xf2ce2000 at 0x48021000
(II) RADEON(0): [drm] Closed DRM master.
(WW) RADEON(0): Direct rendering disabled
(II) RADEON(0): Render acceleration enabled for R200 type cards.

glxinfo, however, claims that direct rendering is enabled.

And from /var/log/syslog:

[David Hedberg (david-hedberg)]

I should have done this before reporting the bug of course, but as I had vague memories of acceleration working when trying out an earlier live-cd version of ubuntu "long ago", I downloaded the 5.04 Live CD and tried it out. And it did indeed have working 3D-acceleration.

Comparing the logs seemed to point at the difference lying in 5.04 falling back on pci for the dri, so I added:
 Option "BusType" "PCI"
to my xorg.conf.

With this option added, 3D-acceleration (including compiz which I'm using at the moment) seems to work just fine, and glxgears (the beloved benchmarking tool ;) ) reports fps about 10 times higher than before.

So. Bug closed?

(is there even any use in reporting possibly ppc-specific bugs?)

I experience the same problem with ibook 1.42ghz 14 inch model.
Intrepid was working (with wobbly windows) but upgrade to jaunty beta does not allow compiz to run (same error as above).

However my /etc/X11/xorg.conf is 0 bytes.
