[ltp] T61 suspend to disk / hibernate with nvidia drivers

[Takis Diakoumis]

Hi

i have a T61 with the nvidia nvs 140m.

same experience from here - s2ram is ok s2disk hangs when coming back. 

s2disk using the vesa driver works fine however.

i have trolled both this list, the wiki and the 'wider world' and though
there are some who apparently report that they got it working i have
never been able to and i've tried a ridiculous number of different
approaches (including the ones you mention) all to no avail.

i know its been suggested that we shouldn't get thinkpads with nvidia
video and in hindsight i probably shouldn't have, but some way to
sorting this out would be good. happy to assist where i can - though the
prob could simply lie with nvidia themselves and not much to be done
from this community.

thanks
Takis
