Installing a 64bit guest on a 32bit host?

Hi!

I was just wondering if there any way to install a SUSE 64 bit guest on my 32 bit WInXP host. I am currently using VMWare Server 1.0.3 and I saw some 64bit guest options, but when I boot the virtual machine with the 64bit installer I get a message "You need a 64 bit machine, this is a 32 bits machine"

Thanks in advance,

Pablo.
