--- Comment #2 from Samuel GOUGEON <sgougeon at free.fr> ---
This bug is fixed with Scilab 6.0.1 / win7 64 bits:

--> n=1000; k=10;
--> M=rand(1000,1000);
--> tic; pM1=M^k; toc
 ans  =
   0.2728594

--> tic; 
--> pM2=eye(M);
--> for i=1:k
  >     pM2=M*pM2;
  > end
--> toc
 ans  =
   0.4994109

I get the same ratio on Fedora.
