These are available I guess?

/* PM1x_STS */
#define ACPI_BITMASK_TIMER_STATUS               0x0001
#define ACPI_BITMASK_BUS_MASTER_STATUS          0x0010
#define ACPI_BITMASK_GLOBAL_LOCK_STATUS         0x0020
#define ACPI_BITMASK_POWER_BUTTON_STATUS        0x0100
#define ACPI_BITMASK_SLEEP_BUTTON_STATUS        0x0200
#define ACPI_BITMASK_RT_CLOCK_STATUS            0x0400
#define ACPI_BITMASK_PCIEXP_WAKE_STATUS         0x4000  /* ACPI 3.0 */
#define ACPI_BITMASK_WAKE_STATUS                0x8000

What do they mean?  How would the rtc wakeup be tagged?  Set
ACPI_BITMASK_RT_CLOCK_STATUS?  Anything I can use for ps/2 kbd/mouse
wakeup?  What do you suggest to do when there is nothing usable (such as
qemu monitor command which simply doesn't exist on real hardware)?

thanks,
  Gerd
