Ok, so it's Mandriva 2005 LE x86 and i have installed driver for Xorg (as usual). Everything works fine, acceleration is OK and all other resolutions work with apropriate refresh rate, just not 1280x960 which dissapeared from my list of resolutions and setting it both by fglrxconfig and manually in xorg.conf doesnt help, switching my desktop to lower available resolution. Hope that clears things out a bit
