Ah...well, there's not much that can be done if one has buggy drivers and
has to resort to the software GL renderer. But, for your other card, you
can try moving the symlinks for the DRI modules out of the way if they
point to gallium_dri.so, which is the SW rasterizer:

$ ls -l /usr/X11R7/lib/modules/dri | fgrep gallium
...
lrwxr-xr-x  1 root  wheel        14 Jul 14 08:33 nouveau_dri.so -> gallium_dri.so
lrwxr-xr-x  1 root  wheel        16 Jul 14 08:33 nouveau_dri.so.0 -> gallium_dri.so.0
lrwxr-xr-x  1 root  wheel        14 Jul 14 08:33 r300_dri.so -> gallium_dri.so
lrwxr-xr-x  1 root  wheel        16 Jul 14 08:33 r300_dri.so.0 -> gallium_dri.so.0
lrwxr-xr-x  1 root  wheel        14 Jul 14 08:33 r600_dri.so -> gallium_dri.so
lrwxr-xr-x  1 root  wheel        16 Jul 14 08:33 r600_dri.so.0 -> gallium_dri.so.0
lrwxr-xr-x  1 root  wheel        14 Jul 14 08:33 radeonsi_dri.so -> gallium_dri.so
lrwxr-xr-x  1 root  wheel        16 Jul 14 08:33 radeonsi_dri.so.0 -> gallium_dri.so.0
...

The idea is to see if the same stuff brought in by MesaLib will do better:

$ ls -l /usr/pkg/lib/dri/

Let's hope these are not LLVMsoftpipe rasterizers too...
