With the standard Linux kernel, you can only use 1G-64M since the system uses a bit of 'extra' address space for administration.
You can run the kernel with mem=960M without any trouble. If you feel like it you can hack the kernel to change the 3:1 split to something else (ie. a 2:2 split).
To do that you need to change __PAGE_OFFSET in include/asm-i386/page.h and arch/i386/vmlinux.lds.
All you need to know to succesfully do this operation is in a big fat comment in page.h.
succes,
