It's got nothing to do with acpid, it's just a userspace daemon, anyway.
The real problem is either somewhere in BIOS (and no, it's not in the AML
either) or in the ACPI code. For the record, I get the PWRF also after S3.

And no, I'm not pressing the power button to resume.

ALSA's suspend / resume support is not really complete, judging on my
experience. My impression is that it currently "works" by chance on my
machine (ICH3M - CS4299).

Well, basically, yes, i.e. I'm able to suspend and resume with a DRI app
running, but that's with Radeon-specific patches to the DRM and DRI
modules. On the other hand, even with those patches both pmdisk and Pavel's
swsusp would reboot at resume if X was running during suspend.
