Comment 213 for bug 121653

The issue is fully covered in: ThinkWiki
http://www.thinkwiki.org/wiki/Installing_Ubuntu_7.10_(Gutsy_Gibbon)_on_a_Thinkpad_T60

It works with 7.12 but in my experience it is much slower with XGL than
8.40.1

My T60 suspends perfectly fine changing /etc/default/acpi-support and a
custom build of the kernel (I can provide deb's) with SLAB enabled.
