ATI 4870 and earlier. NO 3D acceleration on Mageia3

Hi!
It seems that Mageia3 doesn't have the non-free drivers for HD4870 and earlier, I used the free drivers but they don't have 3D acceleration
So, I downloaded the legacy drivers from amd site, but when i tried to install...
"glrx installation requires that the system have kernel headers. /lib/modules/3.8.13-desktop-1.mga3/build/include/linux/version.h cannot be found on this system."
I've installed the kernel devel files, kernel source and kernel-userspace-headers packages, but the error persist.
Anyone knows how to install these drivers on Mageia3, or enable 3D acceleration on free drivers?
Thanks!
