See http://lists.ubuntu.com/archives/dapper-changes/2005-November/001972.html.
Matthew is switching to laptop-mode-tools.

http://people.ubuntu.com/~scott/patches/laptop-mode-tools/ has all
patches made to laptop-mode-tools, which would need to be merged into
to debian package. In any case, close coordination with Brad Samwel
(Maintainer of laptop-mode-tools) would be adviceable.

acpi-support Recommends xscreensaver, and it means it. If xscreensaver
is not installed, many scripts will fail to lock the screen etc.

If someone is going to do this, you should always take the latest
version of the package. During the breezy release cycle, a lot of
efford was made to acpi-support to make hotkeys and suspend to ram
working on many laptops. The breezy package features a whitelist of
laptops which are reported to work with suspend to ram. This whitelist
was tested against the breezy kernel, of course, so it may be
advisable to redo all tests with the latest debian kernel.

And it breaks many notebooks, so it was disabled by default in the
breezy package.

> AFAIK the new Sid kernel supports all features (on x86) (suspend, sleep)

hibernating is quite uncritical, acpi-suspend assumes the kernel has
working swsusp. Suspend to ram is challanging, because it works on far
fewer notebooks.

How about asking Matthew Garrett what problems he sees with the
package being in debian? He has taken over maintership of it and does
a really good job keeping it in shape in ubuntu.
