Its loading on kms modeset instead on intel module (module does not exist on your output)
See if fbdev, intel, i915 and i965 are enabled on VIDEO_CARDS with emerge --info. Also, see if they are enabled on xorg-drivers: emerge -pv xorg-drivers.
The log didn't show the freeze, but it can be related to the missing intel module.
