    I've heard of a kernel patch that gives you 3.5GB (leaving 0.5 for
    the kernel) but you're not going to get any more than that without
    buying a 64-bit machine or playing overlay tricks with mmap(). Given
    the price and performance of 64-bit hardware, the former option is
    probably a lot better.
