Here's my logcat for the call issue. basically I guess its the same as everyone else experienced.
this was using your Gretel#3 version posted today.
I couldn't receive a call at all, but made one and connected and talked fine but couldn't bring anything from the call menu back up (screen with the dial pad, end, speaker buttons) and the phone wasn't able to recognize the call ended from the other phone and I couldn't end it myself. The radio and call quality was great for me. There is some stuff at the beginning of this logcat from when I was testing gmail which worked fine, but I saw in an earlier post it wasn't working for someone so I included it.
Thank you for your work on CM7 so far!!
