Another issue I've discovered with this laptop is that it doesn't want to suspend/resume. When I try apm -S or apm -z, it goes into a suspend state and then refuses to come back; I have to hard-shutdown and then reboot it. In fact, the power management as a whole is kind of semi-broken; it won't power off correctly, either, it just resets the machine (CPU throttling works, though I suspect that's entirely internal to the CPU, and the display-brightness hotkeys work.) It also doesn't even notice the lid sensor, even though machdep.apmhalt and machdep.lidsuspend are both set to 1.

dmesg shows that it does recognize an ACPI device, it just doesn't actually work correctly for some reason:

This wasn't much of an issue when it was still stuck on AC power, but now that I've got a battery for it, it'd be nice to be able to take it places and resume from a suspended session rather than having to cold-boot every time. Is there anything I can do to diagnose/fix this?
