           Summary: Radeon KMS on RV250 gets wrong refresh rate.
           Product: Drivers
           Version: 2.5
    Kernel Version: 2.6.33-rc5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: joekowalski@gmail.com
        Regression: No


When booting with KMS disabled, the ati UMS xorg driver properly sets the
display mode to 1400x1050@60.2hz. xrandr reports the following modes:
$ DISPLAY=:0 xrandr
Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 1400 x 1400
VGA-0 disconnected (normal left inverted right x axis y axis)        
LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x
0mm
   1400x1050      60.2*+                                                        
   1280x1024      59.9     60.0                                                 
   1280x960       60.0     59.9                                                 
   1280x854       59.9                                                          
   1280x800       59.8                                                          
   1280x720       59.9                                                          
   1152x768       59.8                                                          
   1024x768       60.0     59.9                                                 
   800x600        60.3     59.9                                                 
   640x480        59.9     59.4                                                 
S-video disconnected (normal left inverted right x axis y axis)

However when booting with KMS enabled, all that appears is a black screen.
After verifying that fbcon is built into the kernel and that KMS is
initializing, I also found that the xserver had started up, but still with a
blank screen. After blindly logging in, I ssh'd into the box, and found the
following xrandr modes: 
$ DISPLAY=:0 xrandr
Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 4096 x 4096
VGA-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x
0mm
   1400x1050      60.5 +   60.0*
   1280x1024      59.9     60.0
   1280x960       60.0     59.9
   1280x854       59.9
   1280x800       59.8
   1280x720       59.9
   1152x768       59.8
   1024x768       60.0     59.9
   800x600        60.3     59.9
   848x480        59.7
   720x480        59.7
   640x480        59.9     59.4
S-video disconnected (normal left inverted right x axis y axis)

It appears when using KMS, the correct refresh rate for the 1400x1050
resolution  isn't found and instead is a rate that doesn't work with this panel
gets setup, resulting in a blank screen.

Forgot to add: Switching modes under kms with xrandr to a resolution below
1400x1050 results in a working display, although at a poorer resolution.
Switching back to the 1400x1050 mode results in a black screen again.

Under KMS you have two 1400x1050 modes:
LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x
0mm
   1400x1050      60.5 +   60.0*

For some reason, 1400x1050@60 is being selected (marked with the *) while
1400x1050@60.5 is the panel's preferred mode (marked with the +).  Does
selecting 1400x1050@60.5 with xrandr work?  e.g.,
xrandr --output LVDS --mode 1400x1050 --rate 60.5

Okay, after boot it does default to the 60.5 rate, but only displaying the
black screen:
$DISPLAY=:0 xrandr

After switching to a different resolution or to the 60.0 rate (still a black
