My x201i:
Model: 3249A64
CPU: Intel(R) Core(TM) i3 CPU       M 380  @ 2.53GHz
MainBoard: Intel QM57.
Graphics card  is Intel GMA HD(integration).

/etc/make.conf
......
#KMS
WITH_NEW_XORG="YES"
WITH_KMS="YES"
......

My kernel build with kms, which can support the Intel GMA HD graphics card.
My gui is used KDE 4.8. Everything runs ok, except suspend/resume.

The latest situation:
When I close  LCD，x201i will become to Sleep status.
Sleep LED is light, LCD is close.
But, no button can resume it.
