That just means it just has two bits for manual speed.  The third bit
might mean something else.  And disengaged doesn't seem to work.

Also, tachometer needs to be multiplied by 10.

This is a job for ecdump, looking at what the DSDT writes to the fan
control register, etc.  If any of you feel like helping, please do that.
Documentation on how to use ecdump is in
Documentation/laptop/thinkpad-acpi.txt.
