Puedes probar los drivers para la suse 8.2 de este link. Para la 9.0 y 9.1 seguramente ya tiene soporte incorporado en la distribución.
El "readme" pone esto:
Adding support for ATI U1/A3 and U2/A4 chipsets to radeon driver
----------------------------------------------------------------
Supported are these chipsets:
* U1 (IGP320M) or A3 (IGP320)
* U2 (IGP330M/340M/350M) or A4 (IGP330/340/345/350)
Ati Mobility Raden U1 = IGP320M. El chipstet es una combinación de northbridge con una tarjeta gráfica compatible Radeon 7000.
Informacion en Tom's Hardware del chipset

[22. Jul 2003]: PROGRESS WITH 3D SUPPORT
Progress with 3D support! Hui Yu from ATI is working on a agpgart driver for Radeons based on 320M/340M chipsets. A preliminary version of the driver and a patch for XFree CVS are available.. 4x data rate on IGP320/340 internal graphics is working; Mesa demos, TuxRacer and Chromium run fine, they say. Wouter Bijlsma has ported Hui Yu's driver to compile also under 2.5.x (but the patched X had reported "AGP unavailable"). The patches and more detailed information can be found from
http://bugs.xfree86.org/show_bug.cgi?id=314
No he encontrado nada mas... Lo que esta claro es que Ati no va lanzando drivers como en las otras tarjetas graficas... es una lastima
