The kernel can get on with other things even with msleep(1000). By the way, I noticed that msleep(1000) after turning power off is not needed if a slot doesn't implement power controller (as yours) because power cannot be controlled by software (power would be automatically removed when the adapter is removed). I'll make a fix about this.
