[system] in top at least is the netbsd kernel so its the accumulated 
usage of all of the kernel threads in the system. If you want to see it 
broken down press t in top which displays the threads of processes. 
Should be able to see which kernel thread is taking up your CPU.

From my Linux experiece there isn't a top view that corresponds to the 
netbsd default view as linux top always shows all kernel threads as 
separate processes.
