The kernel parameter is a constant called __PAGE_OFFSET which you can set. You also need to edit arch/i386/vmlinux.lds
The reason why your simulation stopped at 2.3GB is likely that the malloc allocation hit the shared libraries (check with /proc/<pid>/maps). Ways around that are telling malloc to use mmap more aggressively (see the malloc documentation in info libc) or moving the shared libraries up by changing a kernel constant called TASK_UNMAPPED_BASE.
