           Summary: "no screens found" error on startup using git radeon
                    driver
           Product: xorg
           Version: git
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW

When starting X using the git radeon driver, X returns to the console and
errors and warnings are reported in the log.

The attached xorg.conf worked correctly with the previous release of the
driver.

There are some warnings in Xorg.0.log:

The I2C warnings were present in logs using older drivers, but did not result
in any obvious problems.
