In my experience with 3 different ATI graphics chipset based systems and two 
Intel chipset based systems things are not good. Generally 2D is Ok with some
X11 lockups and pixel corruptions with two of the ATI boards. 3D is a different 
story though. None of the graphics cards I have will work with Blender, a fairly 
mainstream 3D app and some other 3D apps that I use and I'm sure that the
X1950 Pro and X1550 won't either as there are some fundamental issues in the
mesa/Xorg code that F11 is based upon. These are getting ironed out in the
latest freedesktop git sources and when/if F11's XOrg/Mesa code is updated
I think things will be better.
Not sure how well accelerated Video is supported ...
I am still stuck with F8 using the ATI propitiatory driver for my 3D apps ...
