Log from xorg 6.8.2 which works

Here is log from working xorg 6.8.2.

What is status of this bug ?
We have another laptop with geode video card this time with 800x480 resolution and we also can't get it with latest xorg.
It is serious regression.
Those laptops are now very popular.

So it seems you tell X to use these sync ranges:
(II) AMD(0): monitor1: Using hsync range of 31.50-55.00 kHz
(II) AMD(0): monitor1: Using vrefresh range of 40.00-70.00 Hz

and then define modelines that don't match:
(II) AMD(0): Not using mode "1024x600_120" (hsync out of range)
(II) AMD(0): Not using mode "1024x600_100" (hsync out of range)
(II) AMD(0): Not using mode "1024x600_85" (vrefresh out of range)
(II) AMD(0): Not using mode "1024x600_75" (vrefresh out of range)
(II) AMD(0): Not using mode "1024x600_50" (hsync out of range)

There's one left:
(**) AMD(0):  Mode "1024x600_60": 49.0 MHz, 37.3 kHz, 60.0 Hz
(II) AMD(0): Modeline "1024x600_60"x60.0   48.96  1024 1064 1168 1312 600 601 604 622 -hsync +vsync (37.3 kHz)

but your "Modes" directive says "1024x600", which doesn't exist.  How
about 'Modes "1024x600_60"' instead?

And then your log from 6.8.2 has yet another modeline:
(**) AMD(0): *Mode "1024x600": 48.1 MHz, 38.1 kHz, 60.3 Hz
(II) AMD(0): Modeline "1024x600"   48.11  1024 1056 1232 1264  600 612 618 631

Ah, yes, in this logs is mess.
I don't have this laptop to provide clean logs.
But I have another one notebook. 
It is the same as the first one but it has smaller screen (800x480).
I will try to describe problem.
On xorg 6.8.2 with some modeline settings amd driver gget the correct resolution.
But in xorg 7.2 when I use the xorg.conf from xorg 6.8.2 in logs I can see that it use this modeline but in kde resolution is too big. I can't see a half of the screen (I don't see a taksbar).

Xorg.log form xorg 6.8.2

On xorg 6.8.2 everything works.

Created attachment 19189 [details]
Xorg.log from xorg 7.2

The same xorg.conf and the resolution is incorrect.
I can't see a half of screen in kde.

In xorg 7.2 and (and latest xorg) I tried every modeline.
It just can't get the 800x480 resolution in real.

A lot of people have similar problems:

I have solved a problem so

in xorg.conf add
