The fix is in for-2.6.32/bug-fixes which I haven't asked Jeremy yet to pull.

You can pull the changes yourself. You need these two fixes:

xen/setup: Inhibit resource API from using System RAM E820 gaps as PCI mem gaps
 (commit 96587057018b3ac0b11bf34b791aaadfc403fc80)
xen/e820: Don't mark balloon memory as E820_UNUSABLE when running as guest
 (commit a8462f56975f672ebd5acad179339d8177840e10)
