Works for me on much the same kit.  As I recall, you need to play with
the CPU etc. settings a bit to find some combination that will boot.
Let's see...

   OS Type  FreeBSD (64 bit)
   As much RAM as you want
   One CPU
     Enable PAE/NX
   VT-x/AMD-V Enabled
   Nested Paging Enabled
     Enable IO APIC
     Hardware clock in UTC time
     Enable absolute pointing device

   IDE Controller --> CD/DVD
   SATA Controller --> HardDrive.vdi

Most of these aren't mandatory other than (I think) IO APIC, but I can't
remember for sure.

I went the whole hog and installed this VM with ZFS as the root
filesystem, which works well enough, but isn't really particularly
clever as the VM only has 1GB RAM.  It's great for testing the v28 ZFS
patches though.

You can just save the .iso to your Mac's hard drive -- I created a
directory ~/Library/System-Images -- then use the VirtualBox media
manager to "mount" the .iso into your VM.  I'd use the DVD .iso simply
because it has more stuff in it.  Since you're not constrained by the
capacity of a physical drive, there's no reason to use anything smaller.
