As far as I know, those libs are required to run bluetooth in the first place, so deleting them would not help to get Bluetooth operable.

Second: On my N900 there is no such thing as hciconfig, I do have hcitool, though.

There is a man page, nevertheless, on hciconfig, to be found here.

Perhaps it helps you.

Personally, I would try and reinstall the osso-module for bluetooth.
