Look inside this ticket http://dev.haiku-os.org/ticket/5722 czeidler has shared his knowledge with us about your driver. I tried with my old Radeon HD 2600 Pro, without success.But yesterday I bought a HD 5550 and now I get a "mirrored" image, full ofglitches. I need a driver to set my 1920x1080 resolution.
If you see something this is a very good sign. That you see something means that you already have mapped the app server output to somewhere in the graphic card framebuffer memory and this is the only purpose for the driver at the moment. I reckon that the output signal is not in sync with the current framebuffer geometry... If you have an external monitor connected take a look at the output part I think I never implemented it correctly because it works different for build in laptop screens (maybe it was just luck that it works for me, I never understood this part), try to compare it with the xorg code. See the DxModeSet and DxModeScale method there is a lot commented out and very fishy!
Also recheck if everything is set correctly for your chipset.
Good luck :-)

There has been some discussion lately on a R1A3, but it seems like it's always such a huge effort that getting it rolling and finding devs volunteering for the various tasks has to overcome quite some inertia...
