Oh sorry, you're quite right. All versions of Xen 3.2 do support non-PAE.
However, the current tip of the linux-2.6.18-xen.hg repository does not.
What you should do within that repository is 'hg update xen-3.2.0': this
will revert your repository to a version which is old enough to support
building as non-PAE. Another thing which might work instead, and let you
keep other more recent changes and fixes, is 'hg export 616 | patch -Rp1'.
