I forgot to include the thinkpad_acpi messages during boot:

thinkpad_acpi: ThinkPad ACPI Extras v0.16
thinkpad_acpi: http://ibm-acpi.sf.net/
thinkpad_acpi: ThinkPad BIOS 1AET62WW (1.18 ), EC 1AHT23WW-1.06a
thinkpad_acpi: acpi_bus_get_device(bay) failed: -19
thinkpad_acpi: disabling subdriver bay

This was with the UltraBay battery inserted.
