Thanks for responding Satish .

I tried the included driver without success.  I noted that 0.13.6 was 
available, and the release notes cited improved kernal 2.6.9 
compatibility, so I downloaded it, built it, and installed it.  That all 
seemed to be painless.

When I couldn't  get the touchpad recognized, I installed using a USB 
mouse.  I have edited the xorg.conf to include touchpad  support, as per 
instructions I found from people who had successfully installed Linux on 
the same model of laptop that I have.  Of course they were not using 
FC3.  If something has changed in that regard I would sure appreciate 
pointers!

I have narrowed down my problem somewhat.  The driver requires device 
nodes /dev/input/event[012], but only 0 and 1 are present.  I have 
created event2 with the correct  major/minoir numbers, but after each 
reboot it is gone again.  Likewise I have done a "MAKEDEV psaux" and 
verified that it worked, but after a reboot this node is also gone again.

Under what circumstances are device nodes removed during a reboot?
