Battery bay hotplug detection is not yet implemented. If you boot with the battery in, then do the swap and back, it will work. I have a local patch that implements it but it's not stable enough to commit. It handled hotplug of lots of devices, and last I remember hung up on lpt hotplug. I think iwasaki@ fixed this with his acpi_dock commit. Now that acpi_dock has been added to -current, it may make sense to re-test my patch. -- Nate
