intel - after KMS - i2c-adapter i2c-0: unable to read EDID block......

Hi.

I have a intel 1915 onboard card.

I have just enabled CONFIG_DRM_I915_KMS in my kernel and followed steps to initiate it outlined here - http://bbs.archlinux.org/viewtopic.php?id=69083

It seems to be working o.k, the speed is about the same in kde desktop effects/compiz as previous, VT switching is much better though!

Haven't tried games as its a work desktop (i'll wait for the boss to go .........)

I am getting these messages since enabling KMS mode - i'm 100% sure it is connected with that as that is the only change I made (as well as getting rid of frame buffer).

Here are the messages I am getting in dmesg:-  (I have enabled ic2 debugging in kernel btw)

I have not had any crashes (only been running for 1 day so far).

Does anyone know what the messages mean ?
