You were correct!
I have a WinME install that I use for games (very seldom), and crashed 
last time I used it, which was, coincidentally about the time I updated 
netbsd.
I tried a clean restart using GENERIC, and no problems - in fact my 
mouse was active from the time my computer started (red light on)
However, I will continue to use the ehci kernel in the future to prevent 
WinME messing with my mouse!
