i915 driver update testing

[Johannes Dieterich]

Dear all,

sorry for cross-posting (I am not subscribed to x11@).

Same behavior for me (i5-3320M on a Thinkpad T430s w/ Optimus support) as
reported by Maurizio.

When boot switches to graphics from text mode, display remains black with
backlight on. I am running the experimental xorg-stack from
https://trillian.chruetertee.ch/svn/ports/branches/experimental which works
with an unmodified r272482 w/o problem (minus the Optimus, obviously).

No entry in Xorg.0.log. /var/log/messages only contains output from
consolekit, saying it waits for a native display on tty 9.

Please let me know if you want me to test anything further.

Best

Johannes
