USB Mouse Changed in 2.2.14

I just got a 2.2.14 kernel compiled from Paul Mackerra's rsync source (thank you
especially Ben Herrenschmidt!).

I have another problem: my USB mouse doesn't seem to work now.  Has the spec
changed?  My XF86Config has

Section "Pointer"
    Protocol    "IMPS/2"
    Device       "/dev/usbmouse"

However, X complains that there is no such device.

/dev/usbmouse seems to be a symlink to hidbp-mse-0

This used to work in 2.2.14pre9.
