i install kernel-2.6.3 and xfree86-4.4.0, i neet install ati-drivers?
because of i run xf86config seting can't OK!
I believe you should get basic functionality using the "ati" driver from XFree86 - not "radeon". I know the XFree86 driver in 4.3.99 works with a Radeon 9600, so I suppose 4.4.0 will work too.
However, you will need to install the proper ATI drivers if you wish to obtain full performance from your card.
