I'm getting the impression they are not very popular! To me it seemed like a
clear advantage to use a mouse with my notebook's built-in bluetooth module
without needing a dongle.

O.k., if you find the time to look into this, I installed hcidump (didn't know
about it until you mentioned it), and here's the output with the "-t" flag (any
others I should use?) during a mouse reconnection:

This is all Greek to me. The whole process took 4.6 seconds (a little less than
the 5-6 seconds I had estimated without actually clocking it, but still
significantly longer than under Windows XP, where the mouse connects in under
one second every time). Most of the delay takes place between the "Remote Name
Req Complete" and reception of the next ACL data. Does that tell you
something?
As far as logs go, during reconnection the only lines that were logged into
/var/log/messages were (any other log files I should check?):
