Yes, kernel-2.6.19-1.2895.fc6 broke PS/2 mouse functionality on some
systems, one of which belonged to me. It took an additional three
updates before an updated kernel was released which fixed the problem
on my system. To date some users report their PS/2 mouse is still
broken.

Since FC5 I have made it a practice of setting "tokeep" to 5. I do not
maintain 5 kernels, but I keep the threshold at 5 for events such as
the one above.
