I was at PDX last week. Both the A/B/C and D/E checkpoints had elite lines. In fact, I used the D/E one and was through in 2-3 minutes (after being microwaved).

The cards the TSO gave you typically have the time on them. You give the card to the folks at the WTMD/MMW and they write the time you go through on it. That way they have data on the checkpoint wait times.
