Yes, that's the right thing to do.
Also, in QEMU you're doing:
if (val & 4) {
qemu_system_reset_request();
return;
}
d->rcr = val & 2; /* keep System Reset type only */
It looks like d->rcr should be set first to match what hardware does
(writing 0x6 causes a cold reset, and that's what you usually find in
the ACPI tables).
