I got Dell Latitude E6410 with Intel HD and Chi Mei Optoelectronics corp. 14 display, and also got all problems described above. Hasn't any luck with resolution on 11.04.
But upgrade to alpha 11.10 oneric resolved mostly all issues. If work fine without nomodeset.
I think Intel 2011Q1 graphics package update which was added to kernel 2.6.39 is a fix for this problem. Even sleep mode works fine.
Only one issue I found in oneric - system goes to black screen under Unity when second monitor connected to VGA port. But same action works normal under KDE.
