Probably because a post-install script failed during an update, 
preventing removal of the old version.

No. The "FC4" is just something the packager stuck in the "release" tag 
of the package, and isn't really significant anyway.

Yes. Ask rpm to show you the architecture of the packages too:

$ rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}.%{ARCH}\n' mysql

You'll have i386 and x86_64 versions of the same packages.

Remove the old one as follows:

# rpm -e mysql-4.1.11-2.i386 mysql-4.1.11-2.x86_64
