See this thread :
and this one :
Suspend/resume is broken on my Lenovo x220 (amd64) since revision 231797.
To find this regression, I used a kernel patched with KMS patch "all.13.7.patch", as well as the new Xorg and the intel+KMS driver. Suspend/resume breaks at revision 231797 while it works fine until 231796.
To be more precise, suspend does not seem to terminate ; resume make the computer hang.
Over to ACPI team
Following this message :
I can confirm that removing the VESA option from the kernel enables
suspend/resume again. I don't know how the change introduced by rev.
231797 is related to VESA, but it might give a hint.
As removing VESA is only a workaround, I'll leave this PR opened for the
moment. Feel free to close it if you think it can be.

I suspect no one is going to dig into the VESA breakage at this point. Suspend and resume works fine with KMS and vt(4) however on the x220.
