On i386, compile with -march=i586. The i965 driver requires 64-bit atomic
operations and older CPUs lack the needed instructions. The hardware
supported by that driver will never be used together those older CPUs.
This might mean that even the software rasterizer doesn't work anymore on
those. But they're so slow that you probably wouldn't want to anyway.
