I run both 32 bit and 64 bit versions of Vista on my PC without any issue.
Just create another partition for your 64 bit installation, insert the 64
bit DVD and make sure you install the 64 bit to the new partition. When you
reboot a menu will appear giving you the option to boot to either the 32 bit
or 64 bit versions of Vista.
You might like to download VistaBootPro (freeware) (www.vistabootpro.org)
and click on the 'Manage OS entries' From here you can rename the operating
systems so that you know which one is 32 bit and which is 64 bit. Obviously,
installing 64 bit last will mean that the first option on our menu is the 64
bit system, however, as they are both named the same, i.e. Microsoft Windows
Vista it is better to rename them so you know which is which.
