Relevant slice of /var/log/messages

I've trawled through my remaining logs, and after the initial error they really
don't get any better than:

Aug  6 15:46:43 lantern kernel: [drm:r500_hw_i2c_xfer] *ERROR* failed to get
i2c bus

I was originally trying to get my HD4650 card to drive my HDTV, while leaving
my 1920x1200 monitor and LVDS panel driven by the internal M66GL chip. However,
I'm not sure that I succeeded. More likely, I accidentally pushed XRandR into a
configuration that the HW I2C was unable to handle gracefully instead.
