Receiving ACPI notifications generically
It seems that Acer laptops send an ACPI notification when bay devices are hotplugged (Notify (\_SB.PCI0.IDE0.SECN.BAY1, 0x01)). Obviously, I /could/ catch this by writing a small driver that hooks the notification and then use that to send an ACPI event. Is there any way to do this from userspace? Can the generic hotkey driver be subverted in this way?

Please send me output of acpidmp, then I can show you an example how to configure generic-hotkey-driver for this case. BTW, we need to add battery-hotplug code to respond this event. Thanks,

I'm afraid I don't have the machine to hand (and so can't send a full acpidmp), but here's the DSDT:

Huh, is this ide-bay-hotplug?

Try this:
echo "0:\\_SB.PCI0.IDE0.SECN.BAY1::\\_SB.PCI0.IDE0.SECN.BAY1::1:1" > event_config
