The listed modes have no info on the sync pulse parameters. Other than
trying xvidtune or your own modelines, the last resort is to see if your
monitor is still working properly by connecting it to a windows system
with a windows driver.

(**) RADEON(0): Default mode "1024x768": 78.8 MHz,       60.1 kHz,     75.1 Hz
                                          ^ pix.freq      ^ horz.freq   ^ vert.freq

(II) RADEON(0): Modeline "1024x768" 78.80       1024                 1040             1136          
1312
                                     ^ pix.freq  ^ end of H.visible   ^ H.pulse start  ^ H.pulse
end  ^ end of H.invisible
                768                 769               772             80
                 ^ end of V.visible  ^ V.pulse start   ^ V.pulse end   ^ end of V.invisible (should
be 808???????)

Maybe you have some typos:
