This is the ideal solution. It works fine with the caveat that
you have to be very aware of the virtual memory map of your board
port when doing this. On ppc32, we have very fine grained options
for manipulating this and other parameters under Advanced Options.
If the original poster can provide more details then we can tell
him the exact settings to use.
