says under 7.1 NVIDIA-INSTALLER
Why does NVIDIA not provide RPMs?
"... These repackaged NVIDIA drivers are likely to inter-operate best with 
the Linux distribution's package management technology. For this reason, 
NVIDIA encourages users to use their distribution's repackaged NVIDIA 
driver, where available."

AMD Software End User License Agreement
"(d)   In addition to the license terms above, with respect  to  portions 
of the Software in source code or binary  form  designed  exclusively  for 
use with the Linux operating system ("AMD Linux Code"), you  may  use, 
display, modify, copy, distribute, allow others to  re-distribute, 
package  and  repackage such AMD Linux Code  for  commercial  and 
non-commercial purposes, provided that:"

So I read this as, redistribution is fine with at least Nvidia and AMD.
