The current situation seems to me not ideal and rather complicated.  You 
said bthidd injects messages directly to kernel.  I don't know what the 
consequences are but I noticed the following ... When I run moused my BT 
mouse works in console (except double clicks etc.).  Unfortunately, 
because I wanted extra functionality from my Synaptics touchpad I 
installed x11-drivers/synaptics port which required disabling moused 
which handled the touchpad as ps/2 mouse.  Now synaptics works great in 
X11 but it doesn't work in console at all and my BT mouse doesn't work 
in console either.  But if I plug in a USB mouse devd runs moused and 
suddenly my BT mouse works in console too.  Funny but very inconvenient, 
I can tell you.  Fortunately I don't work in console that much anymore.

With regards,

Martin
