You may have to change the BIOS setting.  Try booting other 64bit-OSes
to see if they do it better.  At least 4G is recognized on my D510MO box

$ sysctl hw.physmem hw.usermem
hw.physmem: 4262477824
hw.usermem: 3002294272

Try capturing dmesg message with boot -v; choose 4-th or so item which reads
  Boot DragonFly with verbose logging
in the boot menu.  You'll get something like the following at the beginning
of your dmesg message.
