I am using nvidias (closed source) driver, but the problem is that I
can't suspend.  There seems to be problem with nvidia on resumes that
can be solved by starting a fake x server, but I never get that far.
  The problem I run into when suspending is something "... panic ...
request while ide blocked ...".  I've found old references to this
problem, but no recent ones so I assume it works for most people.

Thanks for mentioning agpgart, I'll see if I'm using it and try to
dissable it if so.  Now that you mention it I recall some (other?)
problem mentioned in nvidias docs regarding agpgart...  Sudenly it feels
like a good day to quit work early (as the laptop is left at home;-)

The best,
