This works on 3.5 SP1 32-bit. I'm not sure if field sizes are the same on 64-bit - you might have to adjust the types and/or offsets if they are not.

Using reflect, how do you set the value of a struct field?
... false, calling Set or any
type-specific setter (e.g., SetBool,
SetInt64) will panic.
We need to make sure we can Set the struct field. For example,
package main
import (
