I found that the dri had been disable, even though I have Option "AGPMode" "4",
is there anywhere I could solve this problem? Or what should I check to clarified this problem?
AND, also I had try to use ATI fglrx driver, which have dri on dual-head mode,
but the output of 2nd-screen is a totaly mess, any icons, any details on the 2nd-screen are unreadable,
and when the mouse move on 2nd-screen, I just see a bunch of color pixels moving. The xorg.conf is configured by fglrxconfig.
Clone-mode on both driver do have dri, but too bad, I don't know how to let 1st-screen with 1400x1050
while 2nd-screen at 1024x768.
Thanks to any comment.

Get the offical driver from ati.com and use fglrx config it generates a working dual head accelerated config.
