The continuation of the saga that is one of my previous blog entries. I have been using "the other" OS for a while now, and have not noticed that my Linux did not use the correct resolution until I tried to view some pictures on it and they were odd shaped to say the least ;)
So I checked and surely the screen resolution was set to 1280x1024 and would not budge to anything higher (even if manually inserted as Modes line into the xorg.conf). After googling for a while I stumbled upon this and this site.
Sadly the radeonhd driver can not offer 2D and 3D acceleration yet, but I am not that much into games so I don't mind right now... If I need 3D I can still switch to fglrx driver (on 1280x1024 max).
Vieos work quite ok on xshm driver for xine and work ok in Kaffeine (mplayer does not perform ok - neither video nor alsa seems to be ok with it).
glxgears runs on about 600 in windowed mode and drops to about 90 in full screen mode.
If you had better results with the specified card please don't hesitate to leave me a note...
