Do you have a mixed 64b xen/ 32b dom0 stack? If so, it is quite possible
vbetool was not built to use the right emulation library. Like I mentioned in
an earlier thread, XCI build tree takes care of issues of this kind. You might
want to use that or build vbetool with the right emulation library and hope no
other component in your environment is impeding S3 or causing further issues
with respect to host S3...
