Two channels up
... and upstream power level jumped from 49 dBmV to 51 dBmV.
Edit 9-20-2011: Back to 49 dBmV. I guess they weren't finished tuning things up. The Comcast crews in this area are amazing.
Today's whispers seem to indicate other areas around Seattle might want to powercyle to see what is happening in regard to upstream channel bonding.
Edit 9-28-2011: Modem restarted. Upstream channel bonding is gone. Heard a whisper there were some issues, so the second channel was disabled temporarily. No estimate on when it will return, but I have confidence in "my" network guys.
Edit 10-5-2011: It's back now. Received a heads up to powercycle and, sure enough, I have all my blue lights back (send, receive, and connection to my router). Life is good. --
