Sleep Quirks — Debugged!
David Goodlad: the existing article on the Ubuntu wiki for the T61 says to modify /etc/default/acpi-support, which is only valid for Gutsy. gnome-power-manager in Hardy seems to use the data from the hal-info package instead, now, which is contained in a bunch of xml files in /usr/share/hal/fdi/information/10freedesktop/20-video-quirk-pm*.
This hint lead me to Sleep Quirk Debugger, which enabled me to produce:
<match key="system.hardware.product" string="6457B51"> <!-- Proprietary nVidia driver quirks --> <merge key="power_management.quirk.s3_mode" type="bool">true</merge> <merge key="power_management.quirk.s3_bios" type="bool">false</merge> <merge key="power_management.quirk.save_pci" type="bool">true</merge> <merge key="power_management.quirk.vbemode_restore" type="bool">false</merge> </match>
Sam, did you check ThinkWiki? There is a lot of T61 articles and how-tos there that may be of any use to you. It’s my first source of information when it comes to solve issues with Linux in my (IBM provided) T42.

The T61p page on ThinkWiki is a bit sparse.
The big problem with the T61x lines is that they are more memes than products. They contain one of two different processors, one of two different graphics adaptors, one of three different displays...
The lshal program was a worthwhile discovery:

Nice to know! I’ll remember that if I ran into similar problems when I upgrade to Hardy.

I’m really glad if you’re not giving up on Ubuntu owing to the suspend to RAM issues. I solved mine on my Dell + nVidia a year or so ago, and the Hardy upgrade went ok.
