Maybe you'll be interested in ports/benchmark/unixbench, especially the 
context switch and shell scripts benchmarks?

Interesting results, especially for such an early version of the 
processor (wrt HTT) - I'd expect much lower gain from HTT. While you're 
at it, maybe you could add more results to your benchmark, like change 
the timecounter to TSC, use various gcc optimization flags, twiddle 
machdep.cpu_idle_hlt, use SMP kernel with HTT disabled in BIOS?
