With this board:

01:00.0 VGA compatible controller [0300]: ATI Technologies Inc RV280 [Radeon 9200] [1002:5961] (rev 01)

The right setup for me is:

modeset disabled

and the following xorg.conf file:

---
Section "Device"
        Driver "ati"
        Identifier "Radeon 9200"
        Option "BusType" "PCI"
        Option "AGPSize" "64"
EndSection

Section "Monitor"
    Identifier "Configured Monitor"
EndSection

Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Radeon 9200"
EndSection
---

modeset must be disabled in order to really have BusType and AGPSize parameters taken into account.

Also, EXA should not be activated if I want good performance when scrolling pages in firefox or chromium.
