ATI graphics and Linux on some computers is real problem. I tried fglrx driver , but it doesn't compile in openSUSE 11.2 .
The most recent development is that even radeon driver is no more good for Radeon Xpress 200 built in my laptop. Not that it doesn't work at all, but you have to use strange methods to boot the laptop to the GUI. To be honest, not strange to me, I used startx very often long time ago, but I can imagine what would happen if openSUSE was just installed to try it out. It would be removed from the box faster then it was installed. With so many options out there it would take time to see that visitor coming back.
