We did not do that because Linux and Solaris (as dom0) already had the AML interpreter and it's overkill and redundant to have such a large component in the Xen hypervisor. Since the hypervisor does most of the power management (i.e. P, C, S-state, etc.) getting the info from dom0 today, we might want to reconsider the option.
