The problem with suspend to disk appears to be that it hoses my LVM2 swap partition and at boot I see

  kernel: Unable to find swap-space signature

The swap partition is unusable until I run mkswap on it again. Another possible explanation is that suspend is *supposed* to essentially reformat my swap, and since the resume functionality is not able to recognize it, the partition remains in a format that's unusable for swap space. Anyway, this is speculation; someone who knows swsusp would be able to handle this better than I.

That said, now suspend-to/resume-from RAM are working for me. Per https://launchpad.net/distros/ubuntu/+source/thinkpad/+bug/50324/comments/6, I needed the following options in /etc/default/acpi-support:

  ACPI_SLEEP=true
  MODULES="fglrx" # unload/reload fglrx module when suspending

I do *not* have SAVE_VBA_STATE=true uncommented.
