Comment 39 for bug 139089

Here's how I got suspend to ram working on my T61 with a Quadro NVS 140M

With nvidia 100.14.19:
kernel parameter acpi_sleep=s3_mode

vesa drivers:
acpi_sleep=s3_bios

With both configurations above I have made the following changes (that I'm aware of):
In /etc/default/acpi-support:
SAVE_VBE_STATE=false
POST_VIDEO=false

I'm not using the thinkpad-acpi module, but I don't think that should make much of a difference.
(hibernate is not working with the nvidia driver)
