Maybe around the lines containing 1024x768... ;-)   e.g.:

(II) SAVAGE(0): Not using default mode "1024x768" (hsync out of range)
(--) SAVAGE(0): Chose mode 153 at 70Hz.
(II) SAVAGE(0): Not using default mode "512x384" (hsync out of range)
(--) SAVAGE(0): Chose mode 117 at 75Hz.
(II) SAVAGE(0): Not using default mode "1024x768" (hsync out of range)
(--) SAVAGE(0): Chose mode 153 at 70Hz.
(II) SAVAGE(0): Not using default mode "512x384" (hsync out of range)
(--) SAVAGE(0): Chose mode 117 at 85Hz.
(II) SAVAGE(0): Not using default mode "1024x768" (hsync out of range)
(--) SAVAGE(0): Chose mode 153 at 70Hz.
(II) SAVAGE(0): Not using default mode "512x384" (hsync out of range)

and some lines before:
(II) SAVAGE(0): <default monitor>: Using hsync range of 31.47-53.67 kHz
(II) SAVAGE(0): <default monitor>: Using vrefresh range of 43.48-87.85 Hz

Try to define a wider HSYNC range explicitly in lts.conf (if you are SURE 
that your monitor supports it, e.g.: 30-55 (kHz))

(There is NO WARRANTY that this is the solution for your problem... it is 
only a hint.)
