Comment 9 for bug 748994

I got both suspend and hibernate working again after manually installing an older kernel (2.6.35 - http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-maverick/) If you look in the parent directory you'll see that it's quite an old one so maybe it was a bit of an overkill.

in any case, two-finger scrolling on the touchpad flew out the window pretty much instantly (I remember having defined some custom driver for that in maverick previously), but edge-scrolling still works. Audio and video still work as they did before and I can't see anything obviously wrong otherwise...but i guess a lot of bugs have been squashed since then so a progressively going backwards might be better.

In any case, installation apparently has to be done in a specific sequence:

1 linux-header-xxxxxx-all.deb
2 linux-header-xxxxxxx-(your architecture i386 OR amd64 goes here).deb
2 linux-image-xxxxxxx-(your architecture i386 OR amd64 goes here).deb

then run sudo update-grub to make the option available to you under the "previous linux version" boot option. I dont know if that's helpful in solving the bug, itself but if people need a work-around to the problem in the mean time, this MIGHT be one (no guarantees, since i dont know what im doing half the time!)
