Any chance you could bisect it?
I just experiented a bit and it didn't work with 2.6.34.6 neither with 2.6.33.7. This is why I assume that screen hotplugging never worked with KMS on my R600 - I must have confused it with fglrx which I was also using until now.
And I forgot to say something about the logs I did attach yesterday: the logs are from a system which booted without a second screen attached. After the XSession loaded I plugged in the monitor and enabled it with xrandr.
