You should use the Q35 machine type. With regard to triggering an SMI, one implementation you could refer to is here: http://thread.gmane.org/gmane.comp.bios.edk2.devel/329/focus=332 (ICH9_APM_CNT is 0xB2, etc.) Also, if you use KVM for acceleration, be sure to run a recent enough upstream kernel on the host.
