There is a patch for the 2.6.37 tree (and for the xl and xm tools)
that can fix this, but I am in process of reworking it.

If you really want it, get the patches from 

git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git devel/e820-hole
for the 2.6.37 Linux kernel.

And for the tool stack - see attached patch.

You need to define in your .xm file this attribute:

(or 1 to automatically try to guess - which might fail).
