This is not entirely true. 
An application not only has its own memory component, it also has shared 
libraries and a bunch of other things. If the kernel is PAE aware, the 
application can also avail itself of these features. I was reading a Sybase 
paper on the Adaptive Server Enterprise which does this. But, even if a 
32-bit application itself is not PAE aware, it can utilize then extended 
memory indirectly.
