Rubbish.  It makes a lot of sense for most userspace programs to be
32-bit on a 64-bit PowerPC system.  Unless a program needs to do
64-bit integer arithmetic or access more than 4GB of address space, it
will be smaller and faster as a 32-bit process than as a 64-bit
process.

PowerPC doesn't disadvantage 32-bit code the way that x86-64 and ia64
do.

Paul.
