When using x86-64, LS will run in the 32-bit, since I don't know what they call it, 'partition', and can see all the 32-bit parts, but not the 64-bit specific ones. Currently there is no fix for this. It will require more devs using XP 64, or Vista coming out (obviously, devs are going to get Athlon64 CPUs...:)), so that they can play around and get everything pointed where it needs to go.
