Hi Thomas,

the sysctl names have been changed to match those from NetBSD so that
we can use NetBSD estd. Use 


And call patch -p0 < estd_pkgsrc-1.patch in /usr/pkgsrc, then 
compile and install sysctl/estd.

Alternatively you can manually change the CPU frequency with e.g:

sysctl -w machdep.est.frequency.target=800
