   Reporting from an Acer Centrino Duo, running CURRENT r235266. The 
machine has an nvidia card (Ge7300go). The acpi_video and nvidia modules 
are there.

   I did test it a few times with X running (plain twm) and worked just 
fine. Setting hw.acpi.lid_switch_state=S3 allowed me to use the 
close-the-lid-to-sleep functionality.

   The problem comes when I suspend the machine in the console. The 
machine resumes fine (I can ping and ssh it) but the screen remains 
black. I set hw.acpi.reset_video to 0 or 1 but no go. If I'm in a 
console but X is running, after the resume I can CTRL+ALT+F9 and get my 
video back; then I can return to the console. If I don't have X running, 
I don't know how to get my console back.
