Recent versions of QEMU are placing the ACPI I/O ports starting at 0x600 instead of 0xb000. This broke s3.flat and made vmexit.flat test something else than PMTIMER; the latter matters because PMTIMER is special in that it is not using the big QEMU lock. Using the FADT to fetch the port addresses solves both problems.
