Hi,

according to target-arm/helper.c the MMU is enabled/disabled with 
coprocessor 15.

     if ((env->cp15.c1_sys & 1) == 0) {
         /* MMU diusabled.  */
         *phys_ptr = address;
         *prot = PAGE_READ | PAGE_WRITE;
     } else {
         /* Pagetable walk.  */
     }

It is disabled when QEMU starts...
