You need to enable remapping in the BIOS. The memory between 3-4 GB is partly taken by device space. So you have to re-map that actual RAM there to a position above 4 GB - which is what the BIOS does. Once the memory is above 4 GB you need a 64 bit kernel or a 32 bit kernel with PAE enabled to use it. Works fine for me on several machines, BTW. But the remapping options in the BIOSes are often broken.
