Ooops, should have explained the problem.

The copy code assumes that the interrupt vectors were included in the
virtual address space.  The `firmware' I'm running doesn't do this.

Doing the copy with VM disabled was just one possible way of getting
around this.

BTW, are the MMU trap vectors part of the VM state?  Perhaphs this is
one to throw at p1275.
