I get the same result on my 64 bit Gentoo system but it is definitely
64 bit as I have 64 bit hvm's running:
zcat xen-3.4.0.gz | file -
/dev/stdin: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV),

What does "xm info" return? it should list machine type:
machine : x86_64
Also xen_caps:
xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32
hvm-3.0-x86_32p hvm-3.0-x86_64
