Modified Files:
        src/sys/arch/powerpc/ibm4xx: trap.c

Log Message:
Use lswi/syswi instead of lwz/stw when doing loads/stores since we don't
know the alignment of data being copied.  403 cores have alignment
restrictions on lwz/stw that 405 cores don't have.  lswi/syswi benchmark
at the same speed as lwz/stw on a 405 Walnut.

Fixes problems reported by Juergen Hannken-Illjes on the Explora.
