I am just setting up my new A31 with this exact chip and and using
Testing like you but I have some questions if you don't mind.

1. What is the difference between the Radeon and Vesa drivers?
I have tried them both and I see no difference.

2. Every time I do dpkg-reconfigure xserver-xfree86 and say "yes"
to use kernel framebuffer interface, X is just blank when 
I restart the X server.  I have radeonfb in /etc/modules.
What am I missing?

3. Is it necessary to put in the amount of video RAM?
I always leave it blank when doing the configuration.

4. Whenever I configure for the following display's:
1600x1200 1280x1024 1280x960
they all look the same to me.  Which one should I use?

5. My BIGGEST problem is the display is blurry with either the 
vesa or radeon drivers.  I have found that when I press Fn-F7 once, 
the screen goes black.  When I press it a second time, the display comes 
back PERFECTLY crystal clear and brilliant!  The problem is that it is not 
using my whole display.  I have 1/2 inch on the left and right
as black and unused with 1/4 inch top and bottom as well.

6. Which depth should I use?  16 or 24?

7. Can you send my your XF86Config-4 file?  I would like to compare.

Attached is my file.

Thanks
Andy
