devices configured in the xorg.conf are not hotplug-capable. so I guess what
happens is that once the device goes into standby, it's virtually unplugged.
since you've disabled hotplugging, the device isn't added again when it
comes back.

the up/printscreen issue is a mismatch in the evdev and xfree86 scancodes.
that should have been solved in the last couple of releases though. what X,
evdev and xkeyboard-config version are you running?
