Well, it's not a secret that no suspend features are supported on amd64. This is pretty depressing, my notebook even supports S4BIOS and I have to do a lengthy shutdown and boot instead. And let's face it, FreeBSD boots slowly, because nothing happens in parallel and often the time spent during boot is time spent waiting for something, like a network coming up, which is not necessarily required for everything that follows, so other things could be done at the same time.
