Trying to use Radeon driver on Apple eMac

[Joseph Adams]

I wrote a little script and got the Xorg.0.log of every combination.
In some of the tests, I heard Fedora 10 GNOME's startup sound, and
other times I didn't.  IIRC the snippet posted farther down is from a
test where I heard the startup sound.  I also got my dmesg (after
rebooting) which may contain some useful information:

I'll try to briefly post the interesting pieces:

This is the Xorg.0.log of the ConnectorTable option "96,1,0,1,100,2,0,1":

(WW) RADEON(0): Video BIOS not detected, using default clock settings!
(II) RADEON(0): Probed PLL values: xtal: 27.000000 Mhz, sclk:
261.000000 Mhz, mclk: 180.000000 Mhz
(II) RADEON(0): PLL parameters: rf=2700 rd=12 min=12500 max=35000; xclk=36000
(II) RADEON(0): Output VGA-1 has no monitor section
(II) RADEON(0): I2C bus "VGA-1" initialized.
(II) RADEON(0): Output VGA-0 has no monitor section
(II) RADEON(0): I2C bus "VGA-0" initialized.
(II) RADEON(0): Port0:
 Monitor   -- AUTO
 Connector -- VGA
 DAC Type  -- Primary
 TMDS Type -- None
 DDC Type  -- 0x60
(II) RADEON(0): Port1:
 Monitor   -- AUTO
 Connector -- VGA
 DAC Type  -- TVDAC/ExtDAC
 TMDS Type -- None
 DDC Type  -- 0x64
(II) RADEON(0): I2C device "VGA-1:E-EDID segment register" registered
at address 0x60.
(II) RADEON(0): I2C device "VGA-1:ddc2" registered at address 0xA0.
(II) RADEON(0): Output: VGA-1, Detected Monitor Type: 0
(II) RADEON(0): Found color CRT connected to primary DAC
finished output detect: 0
(II) RADEON(0): I2C device "VGA-0:E-EDID segment register" registered
at address 0x60.
(II) RADEON(0): I2C device "VGA-0:ddc2" registered at address 0xA0.
(II) RADEON(0): Output: VGA-0, Detected Monitor Type: 0
finished output detect: 1
finished all detect
before xf86InitialConfiguration
(II) RADEON(0): Output: VGA-1, Detected Monitor Type: 0
(II) RADEON(0): Found color CRT connected to primary DAC
in RADEONProbeOutputModes

The other ones look very similar, except some don't have two (II)
RADEON(0): I2C device "VGA-0:E-EDID segment register" registered at
address 0x** lines.

If you want me to boot into OF to get more information, you'll have to
tell me how :)
