It must be a chipset issue.  When I first switched to a 2.6 kernel I
used a PS/2 mouse.  Then again, it was a dual-Celeron 466MHz box which
is rather more recent than a 166HMz box.

This raises an interesting question.  How much backward compatibility is
removed with each iteration of the kernel?

A 166MHz motherboard with USB?  Wow.  I'd be surprised if the USB
*worked*.  ;-)

The least initial deviation from the truth is multiplied later a
