This isn't going to work. The hardware does nothing to inhibit interrupts in kernel mode, and the system depends on them (performance would be truly dreadful if no interrupt could be taken in kernel mode). The kernel is already using CP0_Status and Count/Compare for its own purposes, which you will be breaking...
