Version 4.0 of Bootcamp for Lion, released July 20, 2011, drops support for all versions of Windows XP and Vista.

It supports 32-bit or 64-bit Microsoft Windows 7 Home Premium, Professional, or Ultimate.

You can run Windows 7 in either 32- or 64-bit versions.

Important to note that Windows XP Professional x64 Edition does not install in Bootcamp. Also, this list isn't correct for Lion. –  ghoppe Aug 22 '11 at 23:27
    
I stand corrected then. –  CajunLuke Aug 22 '11 at 23:35
