I'm on lenny, and just upgraded to version 169.12 of nvidia-glx, which still contains SSE code linked in, and I have an Athlon Thunderbird (pre-palomino) processor, which lacks movups and other SSE instructions.
After looking in the README file in /usr/share/doc/nvidia-glx, and having been clued in that I should set an environment variable in order to disable the extra CPU features that are in nvidia-glx, I tried doing so and still the GL programs I have refuse to run (glxgears etc), dying early with an illegal instruction, even if I run them from the same controlling terminal that I did the export on. I tried also doing the export prior to starting X, but that doesn't seem to help. I didn't have to do this workaround on 100.14.12, which was the previous version I ran up until today's dist-upgrade. And I really shouldn't have to.
