in your .config (for *86 machines) to get 4G of user and 4G of system space.
I so or know how much sense this would make for a 4G of RAM machine. I never
tried it when this machine had only 4G, but that is what is required to get
all 4G in a single user process now that I have 8G.
Those options are not applicable on an x86-64 kernel.
