Well, if you are speaking about the BEV flag from the Status (SR) register (CP0_STATUS aka $12 of the 1st coprocessor)
then it controls the interruption/exception handler place, I don't see the relation with mmu ...

OK, I see, it should be set to 0 by the boot loader so that the TLB exceptions (related to the MMU) goes in RAM. So 
the kernel does not change it actually and hope the boot loader did.
