Hello,


while on my PowerBook OpenGL works (both in a browser as well in minimal
test case glxgears) on my iBook G4 not:

$ glxgears
radeon: Invalid PCI ID.
libGL error: glx: failed to create dri2 screen
libGL error: failed to load driver: radeonsi
LLVM ERROR: Relocation type not implemented yet!
Aborted

the iBook G4 has a slightly minor ATI card:

0000:00:10.0 VGA compatible controller: Advanced Micro Devices, Inc.
[AMD/ATI] RV280/M9+ [Mobility Radeon 9200 AGP] (rev 01)

given dmesg, I see firmware gets loaded:

Ideas what is going wrong?


Thanks,
