If AGP is simply not supported on PowerPC, it would be nice to have a clearer message (or at least a warning).
It is supported, it's just unstable on many PowerMacs.
A patch disabling AGP by default on PowerMacs or even PPC in general probably wouldn't be rejected. :)
Something like the patch: defaulttopci_powerpc.patch ? Should I submit it first on mesa-dev ?
