I appologize for the english post. At least it's germanic? ACPI suspend (S4) to disk works, but standby (S3) does not. It seems to be either missing the "resume" interrupt or not handling it. When going to state S1, the problem seems the same, but, since the monitor does not shut off, I do see some screen output on the resume. It says "Back to C!" and then freezes. In going to standby (S3), the power light on the push button goes out, and the power light on the hinge flashes on and off. This seems proper. Lifting the lid does absolutely nothing. Pressing the power push button brings both power status lights on... but the screen stays blank and there is no disk activity. Not responding to pings verifies that it's not just a video problem. Here's the /var/log/messages output of the standby with verbosity set (15): Sep 30 15:41:53 cwxhost [powersaved][8220]:Info: ACPI Event happened: button/lid LID 00000080 00000001!
