Ok, I see. Xserver and Mesa must be built with the same TLS config. Our
Mesa 7.4 and Xserver 1.6 packages have TLS enabled, while the old Mesa
and your old xserver-xorg-core packages have TLS disabled. So your
config can't work. You need to either wait for Xserver 1.6 to arrive for
powerpc, or downgrade to the previous Mesa for now.

I don't know if we can add some conflicts to prevents your case from
happening.
