Bug#271122: On the X refresh rate problem

[Jukka Laurila <jplauril@cc.hut.fi>]

Apparently the automatically generated configuration file 
contains incorrect sync range directives that override those 
reported by the monitor via DDC. XFree86.0.log says:

(II) RADEON(0): Validating modes on Primary head ---------
(WW) RADEON(0): config file hsync range 28-50kHz not within DDC hsync range 30-110kHz
(WW) RADEON(0): config file vrefresh range 43-75Hz not within DDC vrefresh range 50-160Hz
(II) RADEON(0): SyncMaster: Using hsync range of 28.00-50.00 kHz
(II) RADEON(0): SyncMaster: Using vrefresh range of 43.00-75.00 Hz

XF86Config-4 says:
