3)
My apple keyboard pairs on boot (typing with it now) yet the bluetooth applet is completely unaware of this, and when I attempt to pair my mouse, it doesn't find anything.

4)
I assume the bluetooth application in gnome is suppose to handle all bluetooth pairings?

Other things tried:

/etc/init.d/bluetooth restart doesn't even disrupt the bluetooth pairing of the keyboard

produces log:

This is not really a bug, or it may be a different sort of bug.

Apple firmware simulates the BT keyboard/mouse as USB devices; these are then available after booting Ubuntu through the USB-HID interface (they're listed when running the "sudo lsusb -v" command). Unfortunately, not all functionality is available this way: the fn-key on the keyboard; the scroll ball on the mouse.

In order for them to be treated as Bluetooth devices you must first reset them with the command

$ sudo hciconfig hci0 reset

then (with a temporary USB keyboard/mouse attached) activate the Bluetooth applet and let the BT keyboard/mouse be discovered and paired. Keyboard fn-key and mouse scroll ball are now working, and the "sudo lsusb -v" command does no longer list these devices.

Unfortunately, these BT pairings do not survive a reboot, not even when the line

options hci_usb reset=1

is added to a file like /etc/modprobe.d/options.conf. That would be the real bug...
