Peter:

You should be able to use the mouse, unless there are no IRQs left for 
it.  The dmesg output shows that the mouse is recognized and is 
operational.   Sometimes LINUX can be a little hard to work through this 
problem.  I cannot remember the command to run which device has which 
IRQ, but that may be the next place to look.
