Asterisk on 64 bit computers

Hello. I’m installing for a development server the 1.6 beta2 asterisk version. The computer is a dual Xeon 64 bit EMT64 arch. We are installing over a VXML layer that is a commercial (so no sources) , precompiled 32 bit package. Asterisk runs good on it from sources, but It can’t load the 32 bit VXML module. The error come because it’s 32 bit compiled. Do you have any solution ? Or I have to sacrifice the 64 bit power and install a pure 32 bit kernel ? Thank you.
