fglrx will not be found in the ps list. It is built into the xwindows system.
To see if it is running type:
bash$ glrxinfo | grep render
direct rendering: Yes (this should be the output if 3D is supported.)
If it says 'yes' type:
this will give you your fps or frames per second. It wont be that high since radeon support sucks in linux unfortunately.
A distro like SuSE should give you the option to enable 3D for your card during the installation. Or maybe even after using SaX or YaST. If you can't do it automatically I will help you do it manually. You will need to possibly recompile your kernel because if you wont want to use the kernels direct rendering and there are things you need and need to get rid of most likely, so I hope you installed the kernel source, then you need to install xfree-drm and maybe the ati drivers (I forget what exactly and ati support is weird there is no general way to do it. some cards work better with the kernel rendering, some with the ati drivers in the forums i read people had different levels of success with each) recompile xwindows, and hand edit your Xf86config file, which isnt as hard as it sounds.
