Okay, got it working. I used an almost minimal vanilla 2.6.18 with no
modules. Almost minimal because I included IDE since I have no initram
at hand. But I do not think that makes a difference. I tried out suspend
without IDE a few month ago and it did not work either.

Looking at the console log and bus-messages attached below it seems that
the bus is not initialized during resume. I will try now the early-init
patch I got. Hope that gets more information. Any idea what ACPI-debug
options to set so we see more what happens during suspend? Maybe that
gives a clue too?
