Dmesg of failed boot, showing 2 problems: EDID checksum error and i2c error

With 2.6.39-020639rc1-generic I can boot my Dell D610 Intel GM915 laptop.
But when trying 2.6.39-020639rc7-generic I can see [DRM] error quickly passing in text console, then my laptop screen goes black and I can't see anything.

Is this still a problem in 3.0-rcX / 2.6.39.y ?

Assuming fixed until we hear otherwise.
