Ahhh. Yes. That's what I have been doing.

Right. I already have been booting to single and been using the pm-
suspend command to suspend.

Ubuntu Hardy with the 2.6.28-rc8 kernel.org kernel and Ubuntu Intrepid's
pm-utils release (126.96.36.199-1ubuntu8).

I dream of the day. :-)
One thing I'm thinking about, given that /sys/power/tm_trace is
indicating that the resume problem is in LNXVIDEO, and I have the "i915"
module loaded (it's one that I can not remove as something is always
holding a reference to it) when I suspend/resume, is there any way to not
use that module, at least to see if it's the culprit? Is there a generic
video module I can substitute for it?
