This site has a i386 RPM Repository for CentOS 5.x
Packages include php-5.2.9, php-ffmpeg, and other pecl extensions, http 2.2.13, and mysql-cluster, among others. To use this repository, just download the file named ostalks.repo here.
There is also a small moblin repository in this site. I don’t know what will happen to it when moblin becomes meego, but here’s to hoping it will be a smooth and painless transition.
Update: Moblin rpms are now hosted at ibiblio
Just copy and paste this text for your moblin repository.
