[AccessD] Dual boot Server 2003 X32 and x64

Does anyone know if it is possible to dual boot the x32 and x64 version 
of windows 2k3?  My concern in doing so is that on the one server that I 
run 2k3 x64 on, there are two program file directories, one called 
Program Files the other called Program Files (x86).  It APPEARS that the 
(x86) directory is the 32 bit directory which would imply that the one 
without was the x64, though I have nothing more to base that on than the 
names of the directories inside of each Program Files directory.

I just got a 2nd Phenom quad core and want to convert a second system to 
quad core x64.  The EASIEST way would be to dual boot until I have 
everything I need running in x64 and then cut over.
