Hi and thank you for the tip.
Right after i posted I did update the kernel (fedorafaq.org doesn't mentione it but if we do that code after a clean install, without updating the kernel, the versions of kernel-module-fglrx and ati-fglrx will mismatch, because the previous one will be as old as our kernel, but the last one is always up to date!).
fglrx was correctly installed, but I'm still without 3d. Right now I saw a very interesting forum in:

It was said that some motherboards emulate something by software that controls AGP (newbie talk), and that software is only available in Windows. Still waiting to see if that's my case, and who else is affected.
edit: i forgot to reply, I did that yes, it worked for 2D
