I'm quite happy I chose my T61 with a video card (Intel GMA965) that has
open source drivers.

(Not that my installation was painless.  Far from it...)

Okay, so it hangs somewhere between
/etc/acpi/suspend.d/10-thinkpad-standby-led.sh and /etc/acpi/sleep.sh.

How exactly did you disable video card warm boot?

There are a few options in /etc/default/acpi-support.  SAVE_VBE_STATE is
probably the one you ought to try to disable.

http://people.freedesktop.org/~hughsient/quirk/quirk-suspend-index.html
is a quite good page, but it is primarily tailored for Fedora/Mandriva,
and you have to know how to translate the various suggestions into
Ubuntu-speak...

That's true.  You have to start at /etc/acpi/sleep.sh and read all those
shell scripts.

Try disabling all VBE and DPMS options in /etc/default/acpi-support.

Try with the open-source radeon driver instead of the proprietary one.

Try adding acpi_sleep=3Ds3_bios to the kernel's command line.

This list, thinkwiki.org, Ubuntu's bug tracker.

Actually, if Ubuntu 7.10 doesn't support suspend out-of-the-box on your
laptop, you should report it as a bug at
https://launchpad.net/distros/ubuntu/+bugs
They might fix it before the final release.

Not in Ubuntu.  Hibernate is available from Universe, but by default
Ubuntu uses acpi-support for suspend/hibernation.
