I had similar problems, but were able to fix the suspend bit. I also
have T61p with nvidia 570M. Never managed to fix the hibernation with
proprietary nvidia drivers. What i've done is changed the /etc/default
/acpi-support file to include:
SAVE_VBE_STATE=false
POST_VIDEO=false
SAVE_VIDEO_PCI_STATE=false
and added the following in the Device directive of xorg.conf
Option "NvAGP" "1"
Using these settings I was able to suspend and resume several times in a
row. However, I did notice that if i use opengl applications, my X does
not resume into the existing session, but restarts the X server. I
didn't manage to fix this problem. Perhaps other people can help on
this?
The hibernation bit was never working properly. It seems to resume and I
can see the console screen, but not able to do anything with it. Several
buttons work like Caps / Num lock and I can restart with Ctrl-Alt-Del.
All of these problems seems to relate to Nvidia drivers alone, as I can
successfully Suspend and Resume when I am using vesa X drivers.
