useful all that much. I mean, I thought GL_ARB_vertex_array_bgra support would be widespread.
It is, the issue is probably mostly that the GeForce FX drivers don't see a lot of development from nvidia anymore. This doesn't just affect ARB_vertex_array_bgra, but also things like sRGB texture decode and FBO blits in some cases. Perhaps it's worth a look if there's a newer "legacy" driver from nvidia, but afaik those mostly just fix compatibility with newer X servers, and don't add support for new extensions.
