No sure it can. How?

I understand that.

How can I sanely force chan_sip (and pbx core!) to skip media processing and just perform session control?

The card itself cannot. RTP is only thing this card is capable of.
I can write an external minimal SIP server attached to the card that will run on the same host (or a cluster), then REINVITE-ing will accomplish the task. Except that there will be no way to control the call via Asterisk any more.
