Suspend to RAM (S3 via 3bios) seems to suspend the machine just fine. Only the power button brings it back up, but when it comes back up it seems to hang -- cannot tell as even though the disk seems to have come activity the screen remains black and network apparently doesn't come up. Hope this helps tracking down the ACPI problems. Help appreciated, if more input is needed, please let me know.
