Intel X11 driver doesn't load on zen current

[Andrew Cagney <andrew.cagney%gmail.com@localhost>]

Following up my previous post.  Below is a diff of the Xorg.log from
current and zen/current:

Without zen:
- during boot the kernel flips the screen into 720p
- X successfully loads the intel driver and switches to 720p
with zen:
- the screen starts in 1024x768 and stays in that mode

I'm guessing that the inability to open the device /dev/dri/card0
et.al. eventually leads to the intel driver failing to start
the laptop has HD 3000 builtin graphics.

the plot thickens
