None.  Well, you can be of a LOT of help if you get Intel's iasl (acpi
assembler/disassembler), and disassemble your DSDT and SSDT tables.  Then
you look at ibm-acpi's source, and check if the AML (acpi source language,
it is really an easy one, very simple) of your X60s seems to work
differently than what ibm-acpi expects.

That will probably tell you how to enable/disable bluetooth, after studying
the AML code for a bit.  Since disabling works, you can use that to track
down what piece is missing.

You will likely have to change ibm-acpi code and recompile the kernel to
test out your theories, until you find out what would fix it.
