xorg X11 xorg.conf does not support 'Virtual' parameter

[Dan Sawyer]

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:

enable montype: 2
(II) RADEON(0): I2C device "VGA_DDC:ddc2" registered at address 0xA0.
(II) RADEON(0): I2C device "VGA_DDC:ddc2" removed.
(II) RADEON(0): I2C device "VGA_DDC:ddc2" registered at address 0xA0.
(II) RADEON(0): I2C device "VGA_DDC:ddc2" removed.
(II) RADEON(0): I2C device "VGA_DDC:ddc2" registered at address 0xA0.
(II) RADEON(0): I2C device "VGA_DDC:ddc2" removed.
(II) RADEON(0): DDC Type: 3, Detected Monitor Type: 0
(II) RADEON(0): EDID for output VGA-0
(II) RADEON(0): I2C device "DVI_DDC:ddc2" registered at address 0xA0.
(II) RADEON(0): I2C device "DVI_DDC:ddc2" removed.
(II) RADEON(0): I2C device "DVI_DDC:ddc2" registered at address 0xA0.
(II) RADEON(0): I2C device "DVI_DDC:ddc2" removed.
(II) RADEON(0): I2C device "DVI_DDC:ddc2" registered at address 0xA0.
(II) RADEON(0): I2C device "DVI_DDC:ddc2" removed.
(II) RADEON(0): DDC Type: 2, Detected Monitor Type: 0
(II) RADEON(0): Detected Monitor Type: 0
(II) RADEON(0): EDID for output DVI-0
(WW) RADEON(0): DDC2/I2C is not properly initialized

The kernel is a custom kernel and is identical for both systems. Do you 
get DDC2/I2C errors?
