I have an AMD E450 based laptop running multiple installations of KDE with kernels of 3.2.x series (both .bfs and .pae.bfs)
Bluetooth was relatively working fine with bluez 93 series packages. (I have used relatively because it works fine on a cold boot but waking up from sleep it used to disappear until a reboot)
After upgrading to 101 series all installations loose bluetooth.
hcitool scan says no bluetooth device found.
It is an integrated bluetooth, probably a single chip solution from Broadcom 4313 (that is the wifi chip)
The line corresponding to bluetooth in lsusb reads :
Bus 003 Device 003: ID 0a5c:219c Broadcom Corp.
