Just do it in userspace. > Maybe I'm reading the source wrong, but isn't it the case that some laptops using APM (my IBM thinkpad T41 with acpi=off for instance) suspends without user space interaction when the lid is closed, thus rendering it impossible to send the event from user space? One may even ask whether it's sound to assume that all architectures will be suspended via user space? <snip> > . I'm *not* going to do that from kernel.

Another point is that user space may just use a timer and look at the wall clock to determine when a suspend happens, but that's hardly an elegant architecture. It does save some discussion, though, either way I'll be quiet now and leave you guys to do real work :-) Cheers, David
