While similar address translation changes are also needed in dcdbas, doing them is not sufficient for the driver to work under Xen. It also requires that the issuing on SMIs happens on physical CPU#0, which presently we can arrange for only by using domctl interfaces. I'm not certain however that I could, not being there is any interest in this in the first place, reliably backport to 2.6.18 the hack we use for this in our forward ported trees. Of course, some mechanism will certainly be needed in the pv-ops Dom0 case once that reaches the point where it can be used in products...
