Acer Aspire Timeline Wiki page and Linux Suspend/Resume

There is a great new wiki page for the AspireTimeline laptop model in Ubuntu:
https://help.ubuntu.com/community/AspireTimeline

The Fixes section details the procedure needed to get Suspend/Resume to work:

Possible with new kernel on 64bit Ubuntu

$ wget -c http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630-generic_2.6.30-020630_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-headers-2.6.30-020630_2.6.30-020630_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/linux-image-2.6.30-020630-generic_2.6.30-020630_amd64.deb
$ sudo dpkg -i linux-headers-2.6.30-020630-generic_2.6.30-020630_amd64.deb linux-headers-2.6.30-020630_2.6.30-020630_all.deb linux-image-2.6.30-020630-generic_2.6.30-020630_amd64.deb

Does not seem to work under 32-bit 9.04, 9.10 alpha 2 and alpha 3. Suspend seems to work, but resuming powers off the machine instead. BIOSes versions 1.04 and 1.08 (for 3810t) don't help. Using the "resume-trace" procedure described here does not yield any matches. Unloading all non-essential modules in single user (recovery) mode doesn't fix it.
