Thanks Rashkae.  Problem solved.  I installed the priority driver following the procedure just as you suggested and the interrupt problem was corrected and the mouse appears.

In debugging it looks like I'm having trouble with the video driver (I'm not sure this is at all related to the mouse problem).  I am way over my head at this point and need some help.  I have included some debug output on the video driver showing problem with interrupt handling.  Any guidance/comments would be greatly appreciated.  Thanks.
