Then its a kernel problem.  

It works with the _same_ user space in 2.6.14-rc4-mm1 and fails with 15-rc1-mm2...  
This implies either something is broken in the kernel or udev is not doing its job with 
the new (input?) changes.  Since I switched to udev this summer I have not had to load 
many modules certainly not mousedev.

I'll do a bit of experimenting this weekend to see if I cannot figure out more about what is 
happening.

Thanks for the help
