Chuck - very interesting results. I happen to have a PIII 1Ghz running 
5.4-RELEASE so thought it would be interesting to reproduce your 
numbers. My null and getpid pretty much do, but the time functions seem 
much quicker on my machine - some sort of regression in 5.4-STABLE maybe?

        null function: 0.01578
             getpid(): 0.49136
               time(): 0.83031
       gettimeofday(): 0.78838

However, we are still slower than Linux :-(.

[Running a pretty much stock kernel, except for:

#cpu        I486_CPU
#cpu        I586_CPU

and timer.c is compiled w/o any optimization.]

cheers
