Odd. Works out of the box for me, same Ubuntu 7.04, on a T40p.

That's a subtlety of the shell: output redirection is not affected by=20
prepending "sudo". Either create a shellscript contining those commands and=

call it with sudo, or use tee:
  echo enable | sudo tee /proc/acpi/ibm/bluetooth
  echo disable | sudo tee /proc/acpi/ibm/bluetooth
