Xorg log file

On Slackware 13.1 I have updated xf86-video-ati from git, using X server 1.7.7.  I have a Dell E2009W hooked up to an HD4850, but as soon as Xorg starts, the monitor goes into powersaving mode.  A Westinghouse L1928NV hooked up to the same video card starts up just fine, and Xorg clearly thinks that I have a 1680x1050 monitor left of a 1280x1024 monitor.

This is with KMS disabled.  If I enable KMS, it works fine.

First bad commit is:

bbffd67d3296344e8735b007cdee83146d38369c
atombios: realign digital transmitter/encoder setup with kms

Not sure why this commit would impact UMS, but it does :-)
