feed is one of the pair of contacts, see copper trace running to testconnector nearby.
If it doesn't ask for PIN though it's supposed to, then you either got a bad SIM, or bad SIM contacts (both the pads on SIM and the springs in N900) or your RAPUYAMA modem chips suffer from bad soldering or other chip internal errors.
While you can fix the SIM contact issue by bending and cleaning ([blue rubber-]eraser with sand is good for strong cleaning, a thin unvarnished paperboard - like some business cards are - for gentle cleaning), you can't do much for the soldering problems, except ask some repair shop or send in to Nokia for warranty replacement.
Seems this is a widespread problem.
good luck and cheers
