FWIW, the problems my Dell Latitude had with the external mice I use with it were significantly reduced once I added "psmouse_noext" to the kernel's command line. That one change eliminated all lost sync messages and general craziness after resumes from suspended state. To make the mouse move at proper speed w/o jerkiness I also had to tweak the rate and scaling programmed into it to match 2.4 defaults. (rate 100, scale 2:1) In fairness, only my old Latitude has these PS/2 issues. /Mikael
