It shouldn't have any problem with that at all. I've checked on some of my x86_64 machines running fc2 and yum 2.0.7 in my office and they're getting glibc updates for both i686 and x86_64 by doing a yum update. If you have a specific failure code or something you can cut and paste that might help some. Thanks -sv
