The 601 will get alignment exceptions if operands cross page
boundaries or word operands end in 0xffd - 0xfff.  The latter was what
was happening to me.  Byte operands don't generate alignment
exceptions.

I'm not sure why code in Locore.c didn't cause issues earlier with
ofwboot.xcf.  I seemed only to get the exceptions when booting off the
disk.
