Closing/opening laptop lid results in distortion

["Nick Holmes" <nick_g_holmes_(_at_)_hotmail_(_dot_)_com>]

Today I managed to get X.Org 6.8.2 running on my Dell Latitude C840 laptop 
(3.7-CURRENT). However, whenever I close the lid and re-open it, the display 
is distorted (appears to go split screen through the middle in a different 
resolution causing stretching). I have disabled power management in the BIOS 
and enabled apmd with "-q" in rc.conf. I can get back to my original state 
by changing virtul consoles first to Ctrl+Alt+F4 then back to Ctrl+Alt+F5 - 
The correct resolution then returns. When I press Fn+Esc (Suspend) the 
system suspends fine and wakes up OK too.

dmesg and xorg.conf follows.

Many thanks in advance for any help.

Nick
