grep Accel /var/log/Xorg.0.log
In my case this shows:
(**) RADEON(0): Initializing Acceleration
(II) RADEON(0): Using XFree86 Acceleration Architecture (XAA)
(II) RADEON(0): Acceleration enabled

You can remove GLcore, and dri, they're not supported on 9600XT yet.

This might be slow as well.

According to radeon(4):
Option "RenderAccel" "boolean"
Enables or disables hardware Render acceleration. This driver
does not support component alpha (subpixel) rendering. It is
only supported on Radeon series up to and including 9200
(9500/9700 and newer unsupported). The default is to enable

I think you can remove these five Options, because your hardware doesn't

A couple of years ago, ATI released programming documentation for
radeons up to 9250 (rv280). So those are very well supported by
Xorg. Documentation for newer models was hard/impossible to obtain for a
long time. But recently an open source driver for the r500 chips called
xf86-video-avivo was announced, and AMD has committed itself to release
open source drivers for ATI cards was well.
So you could look for an older 9200 card, or wait for the new drivers.
