I have sent the patch to fix the issue that you pointed out.

The following patch is.
http://lists.xensource.com/archives/html/xen-devel/2009-04/msg00300.html

The patch has already applied in commit 
290b6d18585c887ff2cfa30b239aa2fecfcd0308.

Your changeset seem to be old.
Could you test the latest qemu-xen?

Thanks,
