To help clarify this bug I took a look at the log from gNewSense.
It took a while to reinstall it but I think the information it provided was worth it.
The port detection is failing in the Ubuntu driver.

The BIOS port detection in gNewSense gives the correct type for the ports:
(II) RADEON(0): Bios Connector table: 
(II) RADEON(0): Port0: DDCType-0x60, DACType-1, TMDSType-1, ConnectorType-1
(II) RADEON(0): Port1: DDCType-0x64, DACType-2, TMDSType-1, ConnectorType-2
(II) RADEON(0): Port5: DDCType-0x0, DACType-2, TMDSType-0, ConnectorType-5

Notice that Port1 is ConnectorType-2 which it should be.
The new driver log from Ubuntu doesn`t give this information so there is nothing to compare it to.

Also, the gNewSense gives the correct post assignments:
(II) RADEON(0): I2C bus "VGA-0" initialized.
(II) RADEON(0): I2C bus "DVI-0" initialized.
(II) RADEON(0): Output S-video has no monitor section

And the correct port information:
(II) RADEON(0): Port0:
 Monitor   -- AUTO
 Connector -- VGA
 DAC Type  -- Primary
 TMDS Type -- None
 DDC Type  -- 0x60
(II) RADEON(0): Port1:
 Monitor   -- AUTO
 Connector -- DVI-I       <----- The Ubuntu driver shows VGA even though it is a DVI connector...
 DAC Type  -- TVDAC/ExtDAC
 TMDS Type -- Internal
 DDC Type  -- 0x64
(II) RADEON(0): Port2:
 Monitor   -- AUTO
 Connector -- STV
 DAC Type  -- TVDAC/ExtDAC
 TMDS Type -- None
 DDC Type  -- 0x0

It looks like Ubuntu is finding the wrong connector type and trying to use the DVI port as a VGA port.
This is why the screen shows up in the Display preferences but the actual display is blank.
