You definetly have to say "4GB" here. The Linux Kernel (Gentoo is not responsible for detecting your RAM) will otherwise not access all RAM available. Usually, if you execute "dmesg" the first lines talks about LOWMEM and HIGHMEM. On a machine with 1GB of RAM, it will usually read like that: 750MB LOWMEM 150MB HIGHMEM Using "off" will result in something like that: 750MB LOWMEM 0MB HIGHMEM which is what you're experiencing.
