I patched 2.9 dahdi with the patches supplied by Tim and I can confirm that the autopatch does now work. I can connect to my asterisk PBX (another server) and make calls. So yet another problem fixed. Thanks Jim!
I know Jim wants to do more work on this but unless there is some other significant problem I think it should be a go.
I do have to force the load of snd-pcm-oss though so if you give it a go you might need to add that to /etc/modules.
