Did you check the wiki on "Suspend to RAM"?  It looks like there are a few tools there that should work for your needs.https://wiki.archlinux.org/index.php/SuspendAlso, after I switched to Awesome WM and didn't have the built in functionality to shutdown/reboot, I asked the same question and was lead to using Consolekit & dbus.

What firmware? You shouldn't need to download any additional firmware for this card.You probably don't need to modprobe anything at all - it should be automatic.Have you bothered to read the wiki? https://wiki.archlinux.org/index.php/WifiI can assure you that the driver exhibits no such issues here.
