This does not matter at all. I have stripped down the kernel to a minimum - left out usb, sound etc. now, only few modules are loaded: - unix - ide_core - generic - piix - ide_generic - ide_disk - dm_mod - mbcache - jbd - ext3 So to answer my qouestion: its not needed to compile ide_* directly into kernel. It's enough to have loadable modules instead. echo 3 > /proc/acpi/sleep is doing its job, waking up the machine using powerbutton is working too.
