You'll probably talking about the problems with adbmouse. I have a patch 
for this one. I have also a fixed version of my Xpmac-style 3-mousebutton 
emulation with the "buttons locked before 1st use" problem. I'll forward 
this stuff to Paul later today when I'm home.

What's still NOT fixed in 2.3.15 and really annoying for a lot of users is 
"FB. overflow" aka "macserial: flipbuffer overflow". This was introduced 
somewhere late 2.1 or early 2.2. I think this one is responsible for some 
of the hard crashes reported on linuxppc-users under the "Communicator 
crashes X" thread.

Another problem probably worth a look is the near to zero serial/PPP 
performance during heavy disk activity. One could argue this is a problem 
with my slow 7200/75, but I don't have similar problems under MacOS...
