I don't know if this new major version will be available in the official updates for fedora or in EPEL-6. More, the package available in my repository also provides the official and compatible themes (even if this is against the packaging Guidelines : 1 source = 1 package). So, it is available for fedora 8 to 15 and enterprise linux 4 to 6 (if you have the minimal required php version, also available in the repository).

As always : 
yum --enablerepo=remi install phpMyAdmin

Discover this new version which come with a lot of new features (ajax, chart, preferences, ...), and post your feedback.
