Thanks for your work on this! In the past (months ago) I tried the patch set which didn't work, but the code in -current lets me suspend and resume successfully on my Dell Latitude E6500 (acpiconf -s 3)! I think this is a first for me, of all the laptops I've had, none have ever been able to suspend and resume in a successful or useful way, and I've been jealous of the Thinkpad users that could claim otherwise. I could suspend and resume fine while in the console, then I ran startx and the suspend and resume worked while I was in X with intel graphics, however my system was slow after that resume. I didn't spend much time looking at it since I was at work, and I didn't see any obvious reasons for the slowness (cpu frequency was fine, cx states were C2 or lower (C1), top showed mostly idle, no evidence of an IRQ storm) yet processes ran fairly sluggish (not the mouse or typing though). I didn't go back to console, I just shut down without trying any other situations yet. A tip I want to note for any users who may not have success with their screen on resume: In the past it seemed to help me to have a power-on password set in my BIOS since the BIOS will turn on the screen on resume to ask me for my password. I don't know if it is still helping me, but I've seen in the past where it has.
