I am using an at&t htc aria. But I am trying to help with issues you are having with the ally port to cm6. I downloaded this rom http://androidforums.com/ally-all-things-root/146838-rooted-lite-custom-rom-ally.html so far I have just built a new kernel with a patchset for 2.6.29.6. If someone could try it out for me and report back your findings it would be great. I need to know first if it boots and a logcat of the boot. To do a logcat just run adb logcat >pathtofile and post it to pastebin.com and reply with the link to the pastebin.
