I took some time today to bisect https://launchpad.net/ubuntu/maverick/+source/linux , and have results:

2.6.35-22.33 (OOTB) OK
2.6.35-25.43 OK
2.6.35-25.44-3rdbuild OK
2.6.35-26.46 KO
2.6.35-27.47 KO
2.6.35-28.49 KO
2.6.35-30.53 KO
2.6.35-32.68 (Final) KO

So 2.6.35-26.46 is the culprit, which you can see in https://launchpad.net/ubuntu/+source/linux/2.6.35-26.46 . Please have a look at the changelog, but it shows a few good candidates for the regression:

  ....
  [ Upstream Kernel Changes ]
  * Input: i8042 - introduce 'notimeout' blacklist for Dell Vostro V13
    - LP: #380126
  * ACPI / Sleep: Consolidate suspend and hibernation routines
    - LP: #703228
  * Quirk to fix suspend/resume on Lenovo Edge 11,13,14,15
    - LP: #702434
  * dell-laptop: Add another Dell laptop family to the DMI whitelist
    - LP: #693078
  ....

--> What do you think? What should I test next, and how? Thanks for your help.
