I think the problem starts at a lower level than t_hotswap: if there
wasn't an UltraBay device inserted during boot, then
/proc/acpi/ibm/bay isn't created and no ACPI events are generated on
UltraBay insertion/removal. So it doesn't work even with the new
hotswap-capable ata_piix, which doesn't use ACPI for managing the ATA
interface.
