I somehow doubt that HiPE says enabled without actually being so.
One easy way to test that is to fire up erl and issue the following command:

   1> hipe:c(lists, [verbose]).

If you see something like:

   <HiPE (v 3.7.2)> Compiling: lists
   <HiPE (v 3.7.2)> Options: [verbose,load,icode_ssa_const_prop,...].
   <HiPE (v 3.7.2)> Compiling {lists,'-concat/1-fun-0-',1}
   <HiPE (v 3.7.2)> Compiling {lists,'-filter/2-lc$^0/1-0-',2}
   <HiPE (v 3.7.2)> Compiling {lists,module_info,1}
   <HiPE (v 3.7.2)> Compiling {lists,module_info,0}
   <HiPE (v 3.7.2)> Compiling {lists,rufmerge2_2,6}

The hipe compiler is working OK.  For extra sanity, repeat the previous 
command and if it crashes with a message:

   =ERROR REPORT==== 30-Jun-2009::16:29:05 ===
   Module lists must be purged before loading

then you can be pretty sure that things are *really* working as they 
should.  (This is not a joke.)
