Hi Jason,

I had the same problem and traced it back to pm-utils.

pm-utils is the package used in most distributions to do power
management on behalf of the (now dead) hal and desktops like GNOME and
KDE.
Its problem is that it is full of quirks for old hardware, and on
newer computers it totally breaks them.

For suspending, I use a custom script which does everything for me.
All you have to some is assign some keybinding for it and press it
whenever you want to suspend. There is also a way to specify a custom
script to run for hal power events, but I believe newer distributions
don't rely on hal anymore - so you would have to look at how its done
with Devicekit-power (which is the framework for which hal was
deprecated).

Anyway, try this script and see if your computer suspends and resumes OK.

I have a T400 which I believe has similar hardware to the T61. Having
said that, I do not guarantee it to work. Remember you have to run it
as root. Save the contents between ---------------- as
suspend-script.sh and make it executable (chmod +x suspend-script.sh)
