Finally, the testing on AMD/ATi is made possible! I've found my mistake, I was not cautious enough when was removing old remnants of volatile kernel modules (restricted drivers of ubuntu). I just renamed the dir to fglrx__, which apparently ruined my whole upgrading process, DKMS kernel module of higher version was ommitted... But now I rule the box again! Though seems that only the latest version (fglrx 8-9) lets me start any jme applications, like jcrpg. And so it is running on the brand new card...ready for boarding!!
