Note that enough of those patches have been committed (at least as of r235891) that I was able to perform suspend/resume properly on my laptop (a Dell Precision M4400; video is "NVIDIA GPU Quadro FX 770M (G96GL)", and I use the nVidia driver (ports/x11/nvidia-driver)) without adding more patches. > I've noticed though that the video backlight stays off after resume.

I do not see that behavior, and: g1-227(8.3-S)[7] sysctl hw.acpi.reset_video hw.acpi.reset_video: 0 (Yes, I'm running stable/8 on the present slice. I have stable/9 on another slice. And the experiment I did was with a slice where I had built stable/9 (i386) using clang.) > However, the video mode isn't restored.

I believe that my experience is evidence that if such a shortciming exists, it is not a general one. For me, suspend/resume in stable/9 Just Works (thanks to the hard work of others (such as iwasaki@), of course). > Thanks again for all your hard work!
