I've put logs at http://platan.vc.cvut.cz/ftp/private/radeon/.  It works fine 
with fglrx driver.  With radeon driver from X.org 6.9 it tries to do something, 
but it is hopelessly off - I can see that it attempts to show black/white X 
screen with mouse cursor, but lines are not horizontally synchronized and 
vertically picture is shifted so that vertical blanking is somewhere around 
LCD's 66%.  I can try to grab movie if you want...

ddcprobe.txt is output from ddcprobe, dmesg.txt are radeonfb's boot messages, 
vga.rom is BIOS, and fglrx.xorg.log and radeon.xorg.log are X.org logs.
