The sensor to turn off the screen in calls works in a titanium-only ROM if you use the HTC dialer. If you don't cook in the phone canvas and just try to use the stock WM dialer, the sensor won't work ... but there is a program on XDA that makes it work with the stock dialer, if that is what you want.

I use a ROM with no manila built with Calk's kitchen. I have the Phone Canvas in it and I also use SPB Mobile shell. The proximity sensor works as expected.
