udev on 2.6.14 fails to create /dev/input/event2 on T40 Thinkpad

When I upgraded to 2.6.14 from 2.6.14-rc5, my X server failed to stop.
Investigation revealed it was because my CorePointer was the Synaptics
driver, and the device corresponding to the Synaptics touchpad
(/dev/input/event2 on my laptop) was not being created. Once I manually
created the device with the proper major/minor device numbers, X started
correctly.

A comparison of "udevinfo -e" on 2.6.14-rc5 and 2.5.14 reveals the
following differences. Was this change deliberate? And can it be
reverted?

Thanks,

- Ted
