The kernel has nothing to do with reinitializing the mouse: X has to do that. I was looking into this a few months ago when the installer's mouse probe code stopped working on 2.4, and it became apparent that there is lots of userland code that doesn't do the right thing to handle mouse hot plug reinitialization. gpm and X both need bugfixing in this area. As for the kernel, it needs a few improvements during 2.5: I plan to submit a patch that replaces much of the existing pc keyboard/mouse code with state machine driven code that doesn't block interrupts out for long periods of time, as well as fixing a few of the lockup issues the current driver has.
