Thanks for the note. The major difference (except for the dropped mode
lines messages) in the log files is the system that doesn't work has
the following lines:<br>
<br>
enable montype: 2<br>
(II) RADEON(0): I2C device "VGA_DDC:ddc2" registered at address 0xA0.<br>
(II) RADEON(0): I2C device "VGA_DDC:ddc2" removed.<br>
(II) RADEON(0): I2C device "VGA_DDC:ddc2" registered at address 0xA0.<br>

(II) RADEON(0): Detected Monitor Type: 0<br>
(II) RADEON(0): EDID for output DVI-0<br>
(WW) RADEON(0): DDC2/I2C is not properly initialized<br>
<br>
The kernel is a custom kernel and is identical for both systems. Do you
get DDC2/I2C errors? <br>

because of it.
