Can anything from kernel-space defer a transition to S3 power state?

I'm wondering if there's a way to defer transition to S3 power state, for instance due to pending results from some external module, e.g. crypto-engine?
Picture example scenario: user-space client calls ioctl which is translated by my kernel module into call to external crypto-engine. Halfway thru, my module gets PM_SUSPEND_PREPARE notification. Can I defer the suspension somehow, not permanently, of course?
