well, unplugging the mouse from the KVM and plugging it into the PC's
PS/2 port directly resulted in this in dmesg :

[  567.297724] psmouse.c: Explorer Mouse at isa0060/serio1/input0 lost
synchronization, throwing 1 bytes away.
[  567.807251] psmouse.c: resync failed, issuing reconnect request
[  568.015721] logips2pp: Detected unknown logitech mouse model 87

and after that I see no more resync failed messages and the mouse doesn't stall.

This cures the problem nicely with no obvious ill effects with the
mouse plugged into the KVM...
