if you change up kernels and one of them causes this..then I would do a 
bisect.. but if changing kernels makes no diff, then it's userpsace 
related(but could be wrong) i.e. on my machine I use acpid 
/etc/acpi/lid.sh in there its a simple call to s2ram (works fine(with 
radeon though))looking at some of the distros scripts(no-offense) theres 
loads of stuff in there todo all kinds of calls..

hope this helps.
