The first question is whether or not ACPI could use the current kevent model. The current reactionary response is that kevent is too limited, but that misses the point a bit. The point is that you create kobjects and better integrate with sysfs, and then kevent becomes trivial. So if ACPI better took advantage of sysfs, would kevents be sufficient?
