You're using the 32-bit version, right? The design of x86 architecture (i.e. it's not FreeBSD's problem) is such that a part of memory addresses needs to be set aside for hardware uses, such as the PCI bus, AGP memory & others. This manifests as "holes" in memory that are not accessible to OS. There are two possible solutions: you may try compiling a 32-bit kernel with PAE (but not all drivers support PAE), or install the 64-bit version of FreeBSD.
