question about altivec registers

I understand how to get it working from the processor point of view.  I 
just want to make sure that the linuxppc kernal will not interfere if I 
compile a program that uses these registers.

The bottom line is that I am not looking for any help with the altivec
registers from the kernal.  I just want to be sure that there will not
be any inteference.  If not, great.  I'd just like that insurance.
Thanks for any clarification you can give me.
