It looks like to 3D working with the r300 driver you need set the default
display to 16 in Xorg on gentoo.
rican-linux@ibookG4-gentoo ~ $ LIBGL_DEBUG=verbose glxinfo |grep render
libGL: screen 0 does not appear to be DRI3 capable
libGL: pci id for fd 4: 1002:4e56, driver r300
libGL: OpenDriver: trying /usr/lib/dri/tls/r300_dri.so
libGL: OpenDriver: trying /usr/lib/dri/r300_dri.so
direct rendering: Yes
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
OpenGL renderer string: Gallium 0.4 on ATI RV350
GL_MESA_ycbcr_texture, GL_NV_blend_square, GL_NV_conditional_render,
