Hi, all,
As said on Ubuntu BTS, 
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-geode/+bug/377929
About “unable to set rotation on AMD Geode LX800”, I used Ubuntu 9.10 which 
comes with generic kernel 2.6.31-17 and Xserver 1.6.4, geode-driver 2.11.6, I 
also able to rotate the screen just fine with the default geode driver that 
comes with this distribution using Xrandr. Rotation is working just fine with 
'xrandr'. I used command such as:
> xrandr -o left
> xrandr -o right
> xrandr -o inverted
> xrandr -o normal 
I gave a try with 1.7.1 server on rotation, Geode driver 2.11.7, In our 
platform, the <OUTPUT> name is "default",
(BTW: In general use $ xrandr -q to discover the appropriate output names for 
your configuration, the reference link: 
http://www.thinkwiki.org/wiki/Xorg_RandR_1.2)
When I tried: "xrandr --output default --rotate left". The screen turn to black.
Then tried: "xrandr --output default --rotate normal --auto". The screen return 
to normal.
Because from 1.6.4 server to 1.7.1 server, the part of RandR have been updated 
and changed from source code.
Who know the change about the part of RandR in Xserver 1.7.1?
Thanks,
Hunk Cui
