Process memory map

[Robert Swindells <rjs%fdy2.demon.co.uk@localhost>]

Is there any reason why we need to have a different memory map for
NetBSD/sparc executables when running on 64 and 32 bit hardware ?

The shared libraries are loaded above 0x20000000 on 32 bit and above
0x40000000 on 64 bit. My guess is that we just load at a fixed page
number and don't account for the difference in hw page sizes.
