Hi!
I confirm none of the video drivers should be compiled on ppc32 because
of the lack of atomic64 functions.
In HEAD and stable/10, sys/modules/Makefile should say:
.if ${MACHINE_CPUARCH} =3D=3D "powerpc"
.if ${MACHINE_ARCH} =3D=3D "powerpc64"
_drm2=3D drm2
.endif
.endif
So the drivers are built on ppc64 but not ppc32.
However, in FreeBSD 10.1, the drivers are built for amd64 and i386 only,
as Justin says, not even ppc64.
