sysctl dev.acpi_ibm.0

If it produces a list of values, the module is operating. If not,
something is wrong.
dev.acpi_ibm.0.lcd_brightness SHOULD now work (with the patched DSDT installed).
dev.acpi_ibm.0.volume will not work, but he mixer should, so you can
set the volume buttons to use mixer(1) to adjust the volume
dev.acpi_ibm.0.mute works for me
dev.acpi_ibm.0.thinklight works for me
dev.acpi_ibm.0.fan_speed is valid
dev.acpi_ibm.0.fan_level seems to do nothing
