Is the Gentoo kernel pvops or classic-Xen patches?
Are you sure you are using the classic-Xen
(linux-image-...-xen-{686,amd}) kernel rather than the pvops one
(linux-image-...-686-bigmem, no 64 bit pvops in Lenny)?
I wasn't aware that it applied to the classic-Xen case but the
difference you describe sounds like this commit from upstream pvops:
http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=commit;h=3d65c9488cadd2f11bd4d60c7266e639ece5d0d6
Probably for a 2.6.26 classic-Xen kernel you'd need to adjust the path
to drivers/xen/balloon/balloon.c and perhaps tweak some context a bit
but the concept should still apply.
