Xorg.0.log from KMS boot on 2.6.34-rc3

Just tried kernel 2.6.34-rc3 (not from mainline, self compiled, no source
changes).

Same result as before.

Software is fine, not complaining about anything. But there are some things
that I noticed when booting with KMS enabled:

- no EDID detection of the monitor (driver does that in UMS)

- outputs get swapped finally:
(II) RADEON(0): Output DVI-0 using monitor section Dell 3007WFPHC
(II) RADEON(0): Output DIN has no monitor section
(II) RADEON(0): Output DVI-1 has no monitor section
(II) RADEON(0): Output DVI-0 disconnected
(II) RADEON(0): Output DIN disconnected
(II) RADEON(0): Output DVI-1 connected
(II) RADEON(0): Using exact sizes for initial modes
(II) RADEON(0): Output DVI-1 using initial mode 2560x1600

With UMS this results in DVI-0 becoming connected. The log says previously that
the driver detected the monitor on DVI-1 which is incorrect so the final
swapping corrects the output. With KMS however the initial detection is correct
and the output swapping seems to make it wrong.
