i have thinkpad T23 with docking station.

through the docking station i have external keyboard and mouse connected 
both PS/2.

when i boot FreeBSD when computer is docked, mouse is detected as 
intellimouse, works everything including roller, and both external and 
builtin touchpad works fine.  but when i undock the computer, 
builtin touchpad doesn't work.

other case. if computer was booted undocked, the touchpad is detected as 
generic PS/2 mouse and works. when the computer is docked, both external 
and builtin mouse works, but without roller.

this is probably because builtin mouse is detected as different model than 
external, and driver gets confused.

is there any way to reattach psm driver without reboot?
