No problem to use it.
What not will work is GPMC, not available for 64bit, but you can manage the
GPOs from another machine without problem. See "Compatibility of the out-of-band
(OOB) version of Microsoft Group Policy Management Console (GPMC) with 64-bit
versions of Windows XP, Windows Server 2003 and Windows Server R2" in: http://support.microsoft.com/default...b;en-us;304718
The new coming OS versions will only come in 64bit vesions, as you can see
in Exchange 2007, SBS/EBS 2008, 2008 R2 and Foundation server.
