But... I'm not a "kernel manipulation" specialist... So... how do I get 
the ugen driver loaded? I have no special problem with HID mice or 
keyboards as they are both PS/2 devices on the server... so all I need 
is to load ugen... but do I really need to rebuild a kernel for that? Or 
is there a more "dynamic" way on a running system (I'm OK with having to 
reboot... but rebuilding a kernel... well... haven't done that since the 
SunOS 4.0.3 times... so I'm a bit rusty.).
