Note that apart license issues, since the removing of netscape 4.7X, we no longer includes in main distrib packages for which there aren't sources. NVidia doesn't include them, since even their multi-distrib .src.rpm includes binary only files and libraries and were even compiled with old egcs compilers.
Maybe NVidia, now that they lost the crown of faster 3D card even on newer GeForce FX against ATI, can think to release freely their drivers freely (which I doubt) trying to conquer other markets, like those of Linux 3D workstations. You can try to ask them... Bye. Giuseppe.
