Is it a hard requirement that a x86_64 frysk is able to unwind an i386 process? If you're ok with doing this in a separate (i386) address space, you can use the i386 native version of libunwind, without any code changes.

If you must do this in a x86_64 address space, I would suggest treating i386 the same way you'd treat ppc32 i.e by not using ptrace related code and using your own accessors.
