Try inserting the toshiba module first:
Code:
sudo modprobe toshiba
sudo toshset bluetooth on
There may be some newer way to do this without having to use toshset.
It appears that the toshiba module is no longer loaded automatically by the kernel, since much of the functionality is handled through the newer toshiba_acpi (and using the more general power configuration
acpitool). But I can't see any interface in /proc/acpi/toshiba to enable the bluetooth power.
I don't think that having both toshiba and toshiba_acpi modules loaded will be a problem.
