great, thank you for the reporting the problem and helping with testing. 
i've committed fix to -current and will mfc it shortly.

well, this option specifies how often bthidd(8) should attempt to 
connect to the inactive bluetooth hid devices. that is bthidd(8) goes 
and pro-actively connects to the hid device. but there is one tiny 
detail - bluetooth hid devices have a "reconnect_initiate" flag. if its 
set then bthidd(8) should not attempt to connect to the hid device, but 
rather wait until device connects to it. and, yes, it could take few 
seconds for mouse to reconnect. it has to wake up, establish baseband 
connection and two l2cap channels. so, i do not think you can do 
anything about it.

thanks,
