Well, I've made some progress on this last night by following this

I have the radeon drivers installed and it finds the card:
$ fglrxinfo
display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: MOBILITY RADEON 9000/9100 IGP Series DDR Generic
OpenGL version string: 1.3.4769 (X4.3.0-8.8.25)

glxgears works, but fgl_glxgears does not. Not sure how big of an issue
that is. I have my single laptop display workng, but I can't get the
external display working. I've even tried fglrxconfig, but that config
wouldn't even load the laptop display. (I assume I answered one or more
questions incorrectly).

At the bottom is my single laptop display xorg.conf. Anyone willing to
give me their insight on modifying this for my external flat panel
display? I'd like to get 1280x1024 on the external display and 1280x800
on the laptop display. Not dual head, I just want to close my laptop and
use the external, but be able to open the laptop when I need to (such as
moving to another room, etc). 

Any help is appreciated.
