This was an error on my side, both the i386 and amd64 ports determine available memory using the same method.. they obtain a "memory map" from the BIOS.
It would appear that the remaining memory is mapped above 4GB physical, thus you won't be able to use it until the amd64 platform supports it.
The i386 port will probably never support PAE,PSE36.. 3rd party patches have existed to add support for it, but it'll probably never be supported officially.
So you won't be able to utilize the additional memory in 4.5 or 4.6, but perhaps the developers will work on "bigmem" support for 4.7.
Sorry about that.
