This probably isn't a help, but are you aware of this page? . It look loike it's only patches, so I guess it's not going to be much help.
I've had a bit of a look around and it looks like it probably is an X86 architechture. If this is the case, this will make download selection much easier.
If you are installing a RPM (which should be easy to get hold of if it is X86) use at the console:
rpm -i filename
If it's something like .tar.gz you'll need to decompress it and follow the instructions.
Sorry if you already know this stuff, I don't know how much you know and how much you want to know. If you want to know more just ask.
