Good idea.  

You might also want to try "Goto BLAS" (Google that to find the free
download site).  It can be compiled for a different architecture a lot
quicker than ATLAS, and provides very good performance for both Intel
and AMD architectures.

As you may have already found, once you are using a good BLAS library
with HPL, various compilers or compiler options won't make much
difference in performance.
